Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617464, here are decompositions:

3 + 31617461 = 31617464
7 + 31617457 = 31617464
61 + 31617403 = 31617464
103 + 31617361 = 31617464
181 + 31617283 = 31617464
211 + 31617253 = 31617464
283 + 31617181 = 31617464
331 + 31617133 = 31617464

Showing the first eight; more decompositions exist.
