Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549706, here are decompositions:

43 + 31549663 = 31549706
109 + 31549597 = 31549706
127 + 31549579 = 31549706
367 + 31549339 = 31549706
379 + 31549327 = 31549706
499 + 31549207 = 31549706
523 + 31549183 = 31549706
607 + 31549099 = 31549706

Showing the first eight; more decompositions exist.
