Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549466, here are decompositions:

127 + 31549339 = 31549466
139 + 31549327 = 31549466
229 + 31549237 = 31549466
283 + 31549183 = 31549466
349 + 31549117 = 31549466
367 + 31549099 = 31549466
379 + 31549087 = 31549466
457 + 31549009 = 31549466

Showing the first eight; more decompositions exist.
