Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549708, here are decompositions:

17 + 31549691 = 31549708
41 + 31549667 = 31549708
59 + 31549649 = 31549708
101 + 31549607 = 31549708
257 + 31549451 = 31549708
269 + 31549439 = 31549708
317 + 31549391 = 31549708
431 + 31549277 = 31549708

Showing the first eight; more decompositions exist.
