Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549714, here are decompositions:

23 + 31549691 = 31549714
47 + 31549667 = 31549714
107 + 31549607 = 31549714
167 + 31549547 = 31549714
263 + 31549451 = 31549714
311 + 31549403 = 31549714
761 + 31548953 = 31549714
857 + 31548857 = 31549714

Showing the first eight; more decompositions exist.
