Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593946, here are decompositions:

3 + 31593943 = 31593946
107 + 31593839 = 31593946
113 + 31593833 = 31593946
149 + 31593797 = 31593946
179 + 31593767 = 31593946
227 + 31593719 = 31593946
257 + 31593689 = 31593946
317 + 31593629 = 31593946

Showing the first eight; more decompositions exist.
