Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549574, here are decompositions:

13 + 31549561 = 31549574
163 + 31549411 = 31549574
193 + 31549381 = 31549574
337 + 31549237 = 31549574
367 + 31549207 = 31549574
373 + 31549201 = 31549574
457 + 31549117 = 31549574
487 + 31549087 = 31549574

Showing the first eight; more decompositions exist.
