Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617834, here are decompositions:

7 + 31617827 = 31617834
23 + 31617811 = 31617834
37 + 31617797 = 31617834
71 + 31617763 = 31617834
137 + 31617697 = 31617834
167 + 31617667 = 31617834
251 + 31617583 = 31617834
271 + 31617563 = 31617834

Showing the first eight; more decompositions exist.
