Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549492, here are decompositions:

41 + 31549451 = 31549492
53 + 31549439 = 31549492
89 + 31549403 = 31549492
101 + 31549391 = 31549492
251 + 31549241 = 31549492
311 + 31549181 = 31549492
449 + 31549043 = 31549492
509 + 31548983 = 31549492

Showing the first eight; more decompositions exist.
