Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549016, here are decompositions:

7 + 31549009 = 31549016
19 + 31548997 = 31549016
193 + 31548823 = 31549016
199 + 31548817 = 31549016
277 + 31548739 = 31549016
283 + 31548733 = 31549016
397 + 31548619 = 31549016
439 + 31548577 = 31549016

Showing the first eight; more decompositions exist.
