Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549330, here are decompositions:

3 + 31549327 = 31549330
53 + 31549277 = 31549330
89 + 31549241 = 31549330
149 + 31549181 = 31549330
311 + 31549019 = 31549330
347 + 31548983 = 31549330
563 + 31548767 = 31549330
587 + 31548743 = 31549330

Showing the first eight; more decompositions exist.
