Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617426, here are decompositions:

13 + 31617413 = 31617426
17 + 31617409 = 31617426
19 + 31617407 = 31617426
23 + 31617403 = 31617426
47 + 31617379 = 31617426
53 + 31617373 = 31617426
97 + 31617329 = 31617426
157 + 31617269 = 31617426

Showing the first eight; more decompositions exist.
