Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617460, here are decompositions:

3 + 31617457 = 31617460
11 + 31617449 = 31617460
29 + 31617431 = 31617460
47 + 31617413 = 31617460
53 + 31617407 = 31617460
89 + 31617371 = 31617460
131 + 31617329 = 31617460
167 + 31617293 = 31617460

Showing the first eight; more decompositions exist.
