Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447716, here are decompositions:

43 + 31447673 = 31447716
59 + 31447657 = 31447716
73 + 31447643 = 31447716
89 + 31447627 = 31447716
109 + 31447607 = 31447716
229 + 31447487 = 31447716
239 + 31447477 = 31447716
277 + 31447439 = 31447716

Showing the first eight; more decompositions exist.
