Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597616, here are decompositions:

3 + 31597613 = 31597616
13 + 31597603 = 31597616
67 + 31597549 = 31597616
109 + 31597507 = 31597616
163 + 31597453 = 31597616
199 + 31597417 = 31597616
373 + 31597243 = 31597616
439 + 31597177 = 31597616

Showing the first eight; more decompositions exist.
