Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568632, here are decompositions:

3 + 31568629 = 31568632
71 + 31568561 = 31568632
89 + 31568543 = 31568632
233 + 31568399 = 31568632
239 + 31568393 = 31568632
503 + 31568129 = 31568632
509 + 31568123 = 31568632
701 + 31567931 = 31568632

Showing the first eight; more decompositions exist.
