Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568296, here are decompositions:

29 + 31568267 = 31568296
167 + 31568129 = 31568296
173 + 31568123 = 31568296
269 + 31568027 = 31568296
587 + 31567709 = 31568296
647 + 31567649 = 31568296
653 + 31567643 = 31568296
659 + 31567637 = 31568296

Showing the first eight; more decompositions exist.
