Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617850, here are decompositions:

23 + 31617827 = 31617850
53 + 31617797 = 31617850
137 + 31617713 = 31617850
191 + 31617659 = 31617850
263 + 31617587 = 31617850
317 + 31617533 = 31617850
347 + 31617503 = 31617850
353 + 31617497 = 31617850

Showing the first eight; more decompositions exist.
