Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593976, here are decompositions:

17 + 31593959 = 31593976
23 + 31593953 = 31593976
107 + 31593869 = 31593976
137 + 31593839 = 31593976
179 + 31593797 = 31593976
257 + 31593719 = 31593976
347 + 31593629 = 31593976
443 + 31593533 = 31593976

Showing the first eight; more decompositions exist.
