Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588692, here are decompositions:

13 + 31588679 = 31588692
19 + 31588673 = 31588692
61 + 31588631 = 31588692
89 + 31588603 = 31588692
131 + 31588561 = 31588692
199 + 31588493 = 31588692
229 + 31588463 = 31588692
251 + 31588441 = 31588692

Showing the first eight; more decompositions exist.
