Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617670, here are decompositions:

3 + 31617667 = 31617670
11 + 31617659 = 31617670
41 + 31617629 = 31617670
83 + 31617587 = 31617670
107 + 31617563 = 31617670
137 + 31617533 = 31617670
167 + 31617503 = 31617670
173 + 31617497 = 31617670

Showing the first eight; more decompositions exist.
