Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597766, here are decompositions:

3 + 31597763 = 31597766
37 + 31597729 = 31597766
73 + 31597693 = 31597766
127 + 31597639 = 31597766
163 + 31597603 = 31597766
283 + 31597483 = 31597766
313 + 31597453 = 31597766
349 + 31597417 = 31597766

Showing the first eight; more decompositions exist.
