Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567956, here are decompositions:

73 + 31567883 = 31567956
97 + 31567859 = 31567956
107 + 31567849 = 31567956
137 + 31567819 = 31567956
227 + 31567729 = 31567956
239 + 31567717 = 31567956
257 + 31567699 = 31567956
263 + 31567693 = 31567956

Showing the first eight; more decompositions exist.
