Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597936, here are decompositions:

3 + 31597933 = 31597936
23 + 31597913 = 31597936
59 + 31597877 = 31597936
113 + 31597823 = 31597936
173 + 31597763 = 31597936
197 + 31597739 = 31597936
239 + 31597697 = 31597936
263 + 31597673 = 31597936

Showing the first eight; more decompositions exist.
