Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597608, here are decompositions:

5 + 31597603 = 31597608
37 + 31597571 = 31597608
59 + 31597549 = 31597608
67 + 31597541 = 31597608
101 + 31597507 = 31597608
137 + 31597471 = 31597608
191 + 31597417 = 31597608
197 + 31597411 = 31597608

Showing the first eight; more decompositions exist.
