Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617616, here are decompositions:

29 + 31617587 = 31617616
53 + 31617563 = 31617616
83 + 31617533 = 31617616
113 + 31617503 = 31617616
167 + 31617449 = 31617616
347 + 31617269 = 31617616
449 + 31617167 = 31617616
467 + 31617149 = 31617616

Showing the first eight; more decompositions exist.
