Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617584, here are decompositions:

127 + 31617457 = 31617584
181 + 31617403 = 31617584
211 + 31617373 = 31617584
223 + 31617361 = 31617584
331 + 31617253 = 31617584
571 + 31617013 = 31617584
727 + 31616857 = 31617584
811 + 31616773 = 31617584

Showing the first eight; more decompositions exist.
