Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617306, here are decompositions:

13 + 31617293 = 31617306
23 + 31617283 = 31617306
37 + 31617269 = 31617306
53 + 31617253 = 31617306
67 + 31617239 = 31617306
107 + 31617199 = 31617306
139 + 31617167 = 31617306
157 + 31617149 = 31617306

Showing the first eight; more decompositions exist.
