Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444692, here are decompositions:

11 + 31444681 = 31444692
31 + 31444661 = 31444692
43 + 31444649 = 31444692
61 + 31444631 = 31444692
101 + 31444591 = 31444692
151 + 31444541 = 31444692
239 + 31444453 = 31444692
313 + 31444379 = 31444692

Showing the first eight; more decompositions exist.
