Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549062, here are decompositions:

11 + 31549051 = 31549062
19 + 31549043 = 31549062
23 + 31549039 = 31549062
43 + 31549019 = 31549062
53 + 31549009 = 31549062
79 + 31548983 = 31549062
101 + 31548961 = 31549062
109 + 31548953 = 31549062

Showing the first eight; more decompositions exist.
