Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568116, here are decompositions:

29 + 31568087 = 31568116
89 + 31568027 = 31568116
233 + 31567883 = 31568116
257 + 31567859 = 31568116
347 + 31567769 = 31568116
443 + 31567673 = 31568116
467 + 31567649 = 31568116
479 + 31567637 = 31568116

Showing the first eight; more decompositions exist.
