Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567756, here are decompositions:

47 + 31567709 = 31567756
83 + 31567673 = 31567756
107 + 31567649 = 31567756
113 + 31567643 = 31567756
137 + 31567619 = 31567756
197 + 31567559 = 31567756
359 + 31567397 = 31567756
443 + 31567313 = 31567756

Showing the first eight; more decompositions exist.
