Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568006, here are decompositions:

7 + 31567999 = 31568006
157 + 31567849 = 31568006
193 + 31567813 = 31568006
277 + 31567729 = 31568006
307 + 31567699 = 31568006
313 + 31567693 = 31568006
577 + 31567429 = 31568006
709 + 31567297 = 31568006

Showing the first eight; more decompositions exist.
