Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549552, here are decompositions:

5 + 31549547 = 31549552
53 + 31549499 = 31549552
101 + 31549451 = 31549552
113 + 31549439 = 31549552
149 + 31549403 = 31549552
179 + 31549373 = 31549552
311 + 31549241 = 31549552
509 + 31549043 = 31549552

Showing the first eight; more decompositions exist.
