Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549196, here are decompositions:

13 + 31549183 = 31549196
79 + 31549117 = 31549196
97 + 31549099 = 31549196
109 + 31549087 = 31549196
157 + 31549039 = 31549196
199 + 31548997 = 31549196
373 + 31548823 = 31549196
379 + 31548817 = 31549196

Showing the first eight; more decompositions exist.
