Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549136, here are decompositions:

19 + 31549117 = 31549136
37 + 31549099 = 31549136
97 + 31549039 = 31549136
127 + 31549009 = 31549136
139 + 31548997 = 31549136
313 + 31548823 = 31549136
373 + 31548763 = 31549136
379 + 31548757 = 31549136

Showing the first eight; more decompositions exist.
