Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549670, here are decompositions:

3 + 31549667 = 31549670
7 + 31549663 = 31549670
73 + 31549597 = 31549670
79 + 31549591 = 31549670
109 + 31549561 = 31549670
331 + 31549339 = 31549670
433 + 31549237 = 31549670
463 + 31549207 = 31549670

Showing the first eight; more decompositions exist.
