Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617454, here are decompositions:

5 + 31617449 = 31617454
23 + 31617431 = 31617454
41 + 31617413 = 31617454
47 + 31617407 = 31617454
83 + 31617371 = 31617454
173 + 31617281 = 31617454
353 + 31617101 = 31617454
431 + 31617023 = 31617454

Showing the first eight; more decompositions exist.
