Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617796, here are decompositions:

83 + 31617713 = 31617796
107 + 31617689 = 31617796
137 + 31617659 = 31617796
167 + 31617629 = 31617796
233 + 31617563 = 31617796
263 + 31617533 = 31617796
293 + 31617503 = 31617796
347 + 31617449 = 31617796

Showing the first eight; more decompositions exist.
