Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617826, here are decompositions:

29 + 31617797 = 31617826
113 + 31617713 = 31617826
137 + 31617689 = 31617826
167 + 31617659 = 31617826
197 + 31617629 = 31617826
239 + 31617587 = 31617826
263 + 31617563 = 31617826
293 + 31617533 = 31617826

Showing the first eight; more decompositions exist.
