Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567752, here are decompositions:

11 + 31567741 = 31567752
23 + 31567729 = 31567752
43 + 31567709 = 31567752
53 + 31567699 = 31567752
59 + 31567693 = 31567752
71 + 31567681 = 31567752
79 + 31567673 = 31567752
103 + 31567649 = 31567752

Showing the first eight; more decompositions exist.
