Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568056, here are decompositions:

29 + 31568027 = 31568056
173 + 31567883 = 31568056
197 + 31567859 = 31568056
347 + 31567709 = 31568056
383 + 31567673 = 31568056
419 + 31567637 = 31568056
503 + 31567553 = 31568056
659 + 31567397 = 31568056

Showing the first eight; more decompositions exist.
