Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549586, here are decompositions:

7 + 31549579 = 31549586
349 + 31549237 = 31549586
379 + 31549207 = 31549586
487 + 31549099 = 31549586
499 + 31549087 = 31549586
547 + 31549039 = 31549586
577 + 31549009 = 31549586
769 + 31548817 = 31549586

Showing the first eight; more decompositions exist.
