Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549452, here are decompositions:

13 + 31549439 = 31549452
41 + 31549411 = 31549452
61 + 31549391 = 31549452
71 + 31549381 = 31549452
79 + 31549373 = 31549452
113 + 31549339 = 31549452
211 + 31549241 = 31549452
251 + 31549201 = 31549452

Showing the first eight; more decompositions exist.
