Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568122, here are decompositions:

101 + 31568021 = 31568122
191 + 31567931 = 31568122
239 + 31567883 = 31568122
263 + 31567859 = 31568122
353 + 31567769 = 31568122
449 + 31567673 = 31568122
479 + 31567643 = 31568122
503 + 31567619 = 31568122

Showing the first eight; more decompositions exist.
