Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549052, here are decompositions:

13 + 31549039 = 31549052
43 + 31549009 = 31549052
181 + 31548871 = 31549052
229 + 31548823 = 31549052
313 + 31548739 = 31549052
433 + 31548619 = 31549052
439 + 31548613 = 31549052
709 + 31548343 = 31549052

Showing the first eight; more decompositions exist.
