Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549652, here are decompositions:

3 + 31549649 = 31549652
61 + 31549591 = 31549652
73 + 31549579 = 31549652
241 + 31549411 = 31549652
271 + 31549381 = 31549652
313 + 31549339 = 31549652
571 + 31549081 = 31549652
601 + 31549051 = 31549652

Showing the first eight; more decompositions exist.
