Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595528, here are decompositions:

61 + 31595467 = 31595528
157 + 31595371 = 31595528
277 + 31595251 = 31595528
541 + 31594987 = 31595528
661 + 31594867 = 31595528
829 + 31594699 = 31595528
919 + 31594609 = 31595528
1039 + 31594489 = 31595528

Showing the first eight; more decompositions exist.
