Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549106, here are decompositions:

7 + 31549099 = 31549106
19 + 31549087 = 31549106
67 + 31549039 = 31549106
97 + 31549009 = 31549106
109 + 31548997 = 31549106
283 + 31548823 = 31549106
349 + 31548757 = 31549106
367 + 31548739 = 31549106

Showing the first eight; more decompositions exist.
