Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549592, here are decompositions:

3 + 31549589 = 31549592
13 + 31549579 = 31549592
31 + 31549561 = 31549592
181 + 31549411 = 31549592
211 + 31549381 = 31549592
409 + 31549183 = 31549592
541 + 31549051 = 31549592
631 + 31548961 = 31549592

Showing the first eight; more decompositions exist.
