Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549762, here are decompositions:

11 + 31549751 = 31549762
29 + 31549733 = 31549762
71 + 31549691 = 31549762
113 + 31549649 = 31549762
173 + 31549589 = 31549762
263 + 31549499 = 31549762
311 + 31549451 = 31549762
359 + 31549403 = 31549762

Showing the first eight; more decompositions exist.
