TITLE: How to make a pair of six-sided dice whose sum is always a prime number?
QUESTION [17 upvotes]: In other words, how can I find two sets of six distinct integers $a_1, \dots, a_6 \in \Bbb Z$ and $b_1, \dots, b_6 \in \Bbb Z$ such that $a_i+b_j$ is prime for any $i, j \in \{1, \dots, 6\}$?

REPLY [5 votes]: All the answers here are much larger than necessary. I wrote a computer program to find a set of numbers such that the largest number used is as small as possible. An optimal solution is:
$$A = \{5, 13, 17, 47, 73, 83\}$$
$$B = \{0, 6, 24, 54, 66, 84\}$$
However this has duplicate possible rolls. If this is unacceptable and each combination of rolls must be distinct an optimal solution is:
$$A = \{0, 26, 56, 96, 140, 180\}$$
$$B = \{11, 17, 71, 83, 137, 173\}$$
