Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595992, here are decompositions:

3 + 31595989 = 31595992
23 + 31595969 = 31595992
269 + 31595723 = 31595992
419 + 31595573 = 31595992
509 + 31595483 = 31595992
599 + 31595393 = 31595992
719 + 31595273 = 31595992
773 + 31595219 = 31595992

Showing the first eight; more decompositions exist.
