Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549326, here are decompositions:

89 + 31549237 = 31549326
227 + 31549099 = 31549326
239 + 31549087 = 31549326
283 + 31549043 = 31549326
307 + 31549019 = 31549326
317 + 31549009 = 31549326
373 + 31548953 = 31549326
503 + 31548823 = 31549326

Showing the first eight; more decompositions exist.
