Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617416, here are decompositions:

3 + 31617413 = 31617416
7 + 31617409 = 31617416
13 + 31617403 = 31617416
37 + 31617379 = 31617416
43 + 31617373 = 31617416
163 + 31617253 = 31617416
283 + 31617133 = 31617416
367 + 31617049 = 31617416

Showing the first eight; more decompositions exist.
