Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617474, here are decompositions:

13 + 31617461 = 31617474
17 + 31617457 = 31617474
43 + 31617431 = 31617474
61 + 31617413 = 31617474
67 + 31617407 = 31617474
71 + 31617403 = 31617474
101 + 31617373 = 31617474
103 + 31617371 = 31617474

Showing the first eight; more decompositions exist.
