Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549710, here are decompositions:

19 + 31549691 = 31549710
43 + 31549667 = 31549710
47 + 31549663 = 31549710
61 + 31549649 = 31549710
103 + 31549607 = 31549710
113 + 31549597 = 31549710
131 + 31549579 = 31549710
149 + 31549561 = 31549710

Showing the first eight; more decompositions exist.
