Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617432, here are decompositions:

19 + 31617413 = 31617432
23 + 31617409 = 31617432
29 + 31617403 = 31617432
53 + 31617379 = 31617432
59 + 31617373 = 31617432
61 + 31617371 = 31617432
71 + 31617361 = 31617432
103 + 31617329 = 31617432

Showing the first eight; more decompositions exist.
