Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567996, here are decompositions:

113 + 31567883 = 31567996
137 + 31567859 = 31567996
227 + 31567769 = 31567996
347 + 31567649 = 31567996
353 + 31567643 = 31567996
359 + 31567637 = 31567996
443 + 31567553 = 31567996
569 + 31567427 = 31567996

Showing the first eight; more decompositions exist.
