Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617330, here are decompositions:

37 + 31617293 = 31617330
47 + 31617283 = 31617330
61 + 31617269 = 31617330
79 + 31617251 = 31617330
131 + 31617199 = 31617330
149 + 31617181 = 31617330
163 + 31617167 = 31617330
181 + 31617149 = 31617330

Showing the first eight; more decompositions exist.
