Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549084, here are decompositions:

3 + 31549081 = 31549084
41 + 31549043 = 31549084
101 + 31548983 = 31549084
131 + 31548953 = 31549084
227 + 31548857 = 31549084
317 + 31548767 = 31549084
431 + 31548653 = 31549084
443 + 31548641 = 31549084

Showing the first eight; more decompositions exist.
