Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567882, here are decompositions:

23 + 31567859 = 31567882
113 + 31567769 = 31567882
173 + 31567709 = 31567882
233 + 31567649 = 31567882
239 + 31567643 = 31567882
263 + 31567619 = 31567882
431 + 31567451 = 31567882
569 + 31567313 = 31567882

Showing the first eight; more decompositions exist.
