Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595692, here are decompositions:

5 + 31595687 = 31595692
419 + 31595273 = 31595692
449 + 31595243 = 31595692
503 + 31595189 = 31595692
683 + 31595009 = 31595692
701 + 31594991 = 31595692
761 + 31594931 = 31595692
773 + 31594919 = 31595692

Showing the first eight; more decompositions exist.
