Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595288, here are decompositions:

37 + 31595251 = 31595288
79 + 31595209 = 31595288
229 + 31595059 = 31595288
421 + 31594867 = 31595288
541 + 31594747 = 31595288
607 + 31594681 = 31595288
661 + 31594627 = 31595288
691 + 31594597 = 31595288

Showing the first eight; more decompositions exist.
