Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597752, here are decompositions:

13 + 31597739 = 31597752
23 + 31597729 = 31597752
31 + 31597721 = 31597752
59 + 31597693 = 31597752
79 + 31597673 = 31597752
101 + 31597651 = 31597752
113 + 31597639 = 31597752
139 + 31597613 = 31597752

Showing the first eight; more decompositions exist.
