Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549564, here are decompositions:

3 + 31549561 = 31549564
17 + 31549547 = 31549564
113 + 31549451 = 31549564
173 + 31549391 = 31549564
191 + 31549373 = 31549564
227 + 31549337 = 31549564
383 + 31549181 = 31549564
521 + 31549043 = 31549564

Showing the first eight; more decompositions exist.
