Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617374, here are decompositions:

3 + 31617371 = 31617374
13 + 31617361 = 31617374
193 + 31617181 = 31617374
241 + 31617133 = 31617374
457 + 31616917 = 31617374
487 + 31616887 = 31617374
601 + 31616773 = 31617374
727 + 31616647 = 31617374

Showing the first eight; more decompositions exist.
