Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567792, here are decompositions:

23 + 31567769 = 31567792
83 + 31567709 = 31567792
149 + 31567643 = 31567792
173 + 31567619 = 31567792
233 + 31567559 = 31567792
239 + 31567553 = 31567792
281 + 31567511 = 31567792
479 + 31567313 = 31567792

Showing the first eight; more decompositions exist.
