Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549316, here are decompositions:

79 + 31549237 = 31549316
109 + 31549207 = 31549316
199 + 31549117 = 31549316
229 + 31549087 = 31549316
277 + 31549039 = 31549316
307 + 31549009 = 31549316
499 + 31548817 = 31549316
577 + 31548739 = 31549316

Showing the first eight; more decompositions exist.
