Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82688, here are decompositions:

31 + 82657 = 82688
37 + 82651 = 82688
79 + 82609 = 82688
97 + 82591 = 82688
127 + 82561 = 82688
139 + 82549 = 82688
157 + 82531 = 82688
181 + 82507 = 82688

Showing the first eight; more decompositions exist.
