Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549702, here are decompositions:

11 + 31549691 = 31549702
53 + 31549649 = 31549702
113 + 31549589 = 31549702
251 + 31549451 = 31549702
263 + 31549439 = 31549702
311 + 31549391 = 31549702
461 + 31549241 = 31549702
521 + 31549181 = 31549702

Showing the first eight; more decompositions exist.
