Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549496, here are decompositions:

157 + 31549339 = 31549496
313 + 31549183 = 31549496
379 + 31549117 = 31549496
397 + 31549099 = 31549496
409 + 31549087 = 31549496
457 + 31549039 = 31549496
487 + 31549009 = 31549496
499 + 31548997 = 31549496

Showing the first eight; more decompositions exist.
