Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593966, here are decompositions:

7 + 31593959 = 31593966
13 + 31593953 = 31593966
23 + 31593943 = 31593966
29 + 31593937 = 31593966
97 + 31593869 = 31593966
127 + 31593839 = 31593966
179 + 31593787 = 31593966
199 + 31593767 = 31593966

Showing the first eight; more decompositions exist.
