Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567672, here are decompositions:

23 + 31567649 = 31567672
29 + 31567643 = 31567672
53 + 31567619 = 31567672
113 + 31567559 = 31567672
359 + 31567313 = 31567672
401 + 31567271 = 31567672
431 + 31567241 = 31567672
761 + 31566911 = 31567672

Showing the first eight; more decompositions exist.
