Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595756, here are decompositions:

37 + 31595719 = 31595756
103 + 31595653 = 31595756
163 + 31595593 = 31595756
349 + 31595407 = 31595756
373 + 31595383 = 31595756
547 + 31595209 = 31595756
757 + 31594999 = 31595756
769 + 31594987 = 31595756

Showing the first eight; more decompositions exist.
