Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549632, here are decompositions:

41 + 31549591 = 31549632
43 + 31549589 = 31549632
53 + 31549579 = 31549632
71 + 31549561 = 31549632
181 + 31549451 = 31549632
193 + 31549439 = 31549632
229 + 31549403 = 31549632
241 + 31549391 = 31549632

Showing the first eight; more decompositions exist.
