Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549634, here are decompositions:

37 + 31549597 = 31549634
43 + 31549591 = 31549634
73 + 31549561 = 31549634
223 + 31549411 = 31549634
307 + 31549327 = 31549634
397 + 31549237 = 31549634
433 + 31549201 = 31549634
547 + 31549087 = 31549634

Showing the first eight; more decompositions exist.
