Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567914, here are decompositions:

31 + 31567883 = 31567914
101 + 31567813 = 31567914
173 + 31567741 = 31567914
197 + 31567717 = 31567914
227 + 31567687 = 31567914
233 + 31567681 = 31567914
241 + 31567673 = 31567914
271 + 31567643 = 31567914

Showing the first eight; more decompositions exist.
