Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549234, here are decompositions:

53 + 31549181 = 31549234
191 + 31549043 = 31549234
251 + 31548983 = 31549234
281 + 31548953 = 31549234
467 + 31548767 = 31549234
491 + 31548743 = 31549234
557 + 31548677 = 31549234
593 + 31548641 = 31549234

Showing the first eight; more decompositions exist.
