Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567762, here are decompositions:

53 + 31567709 = 31567762
89 + 31567673 = 31567762
113 + 31567649 = 31567762
251 + 31567511 = 31567762
311 + 31567451 = 31567762
449 + 31567313 = 31567762
491 + 31567271 = 31567762
521 + 31567241 = 31567762

Showing the first eight; more decompositions exist.
