Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617384, here are decompositions:

5 + 31617379 = 31617384
11 + 31617373 = 31617384
13 + 31617371 = 31617384
23 + 31617361 = 31617384
101 + 31617283 = 31617384
103 + 31617281 = 31617384
131 + 31617253 = 31617384
251 + 31617133 = 31617384

Showing the first eight; more decompositions exist.
