Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549152, here are decompositions:

53 + 31549099 = 31549152
71 + 31549081 = 31549152
101 + 31549051 = 31549152
109 + 31549043 = 31549152
113 + 31549039 = 31549152
191 + 31548961 = 31549152
199 + 31548953 = 31549152
281 + 31548871 = 31549152

Showing the first eight; more decompositions exist.
