Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549166, here are decompositions:

67 + 31549099 = 31549166
79 + 31549087 = 31549166
127 + 31549039 = 31549166
157 + 31549009 = 31549166
349 + 31548817 = 31549166
409 + 31548757 = 31549166
433 + 31548733 = 31549166
547 + 31548619 = 31549166

Showing the first eight; more decompositions exist.
