Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549610, here are decompositions:

3 + 31549607 = 31549610
13 + 31549597 = 31549610
19 + 31549591 = 31549610
31 + 31549579 = 31549610
199 + 31549411 = 31549610
229 + 31549381 = 31549610
271 + 31549339 = 31549610
283 + 31549327 = 31549610

Showing the first eight; more decompositions exist.
