Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615996, here are decompositions:

3 + 31615993 = 31615996
17 + 31615979 = 31615996
23 + 31615973 = 31615996
149 + 31615847 = 31615996
233 + 31615763 = 31615996
239 + 31615757 = 31615996
557 + 31615439 = 31615996
593 + 31615403 = 31615996

Showing the first eight; more decompositions exist.
