Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549482, here are decompositions:

31 + 31549451 = 31549482
43 + 31549439 = 31549482
71 + 31549411 = 31549482
79 + 31549403 = 31549482
101 + 31549381 = 31549482
109 + 31549373 = 31549482
241 + 31549241 = 31549482
281 + 31549201 = 31549482

Showing the first eight; more decompositions exist.
