Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549562, here are decompositions:

151 + 31549411 = 31549562
181 + 31549381 = 31549562
223 + 31549339 = 31549562
379 + 31549183 = 31549562
463 + 31549099 = 31549562
523 + 31549039 = 31549562
601 + 31548961 = 31549562
691 + 31548871 = 31549562

Showing the first eight; more decompositions exist.
