Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615936, here are decompositions:

17 + 31615919 = 31615936
89 + 31615847 = 31615936
173 + 31615763 = 31615936
179 + 31615757 = 31615936
347 + 31615589 = 31615936
353 + 31615583 = 31615936
593 + 31615343 = 31615936
719 + 31615217 = 31615936

Showing the first eight; more decompositions exist.
