Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617344, here are decompositions:

61 + 31617283 = 31617344
163 + 31617181 = 31617344
211 + 31617133 = 31617344
271 + 31617073 = 31617344
331 + 31617013 = 31617344
457 + 31616887 = 31617344
487 + 31616857 = 31617344
571 + 31616773 = 31617344

Showing the first eight; more decompositions exist.
