Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567846, here are decompositions:

137 + 31567709 = 31567846
173 + 31567673 = 31567846
197 + 31567649 = 31567846
227 + 31567619 = 31567846
293 + 31567553 = 31567846
419 + 31567427 = 31567846
449 + 31567397 = 31567846
797 + 31567049 = 31567846

Showing the first eight; more decompositions exist.
