Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515596, here are decompositions:

19 + 31515577 = 31515596
37 + 31515559 = 31515596
313 + 31515283 = 31515596
379 + 31515217 = 31515596
523 + 31515073 = 31515596
727 + 31514869 = 31515596
757 + 31514839 = 31515596
907 + 31514689 = 31515596

Showing the first eight; more decompositions exist.
