Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568374, here are decompositions:

17 + 31568357 = 31568374
41 + 31568333 = 31568374
107 + 31568267 = 31568374
251 + 31568123 = 31568374
347 + 31568027 = 31568374
353 + 31568021 = 31568374
443 + 31567931 = 31568374
491 + 31567883 = 31568374

Showing the first eight; more decompositions exist.
