Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567976, here are decompositions:

127 + 31567849 = 31567976
157 + 31567819 = 31567976
163 + 31567813 = 31567976
277 + 31567699 = 31567976
283 + 31567693 = 31567976
373 + 31567603 = 31567976
463 + 31567513 = 31567976
547 + 31567429 = 31567976

Showing the first eight; more decompositions exist.
