Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549074, here are decompositions:

23 + 31549051 = 31549074
31 + 31549043 = 31549074
113 + 31548961 = 31549074
251 + 31548823 = 31549074
257 + 31548817 = 31549074
307 + 31548767 = 31549074
311 + 31548763 = 31549074
317 + 31548757 = 31549074

Showing the first eight; more decompositions exist.
