Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593846, here are decompositions:

7 + 31593839 = 31593846
13 + 31593833 = 31593846
59 + 31593787 = 31593846
79 + 31593767 = 31593846
83 + 31593763 = 31593846
127 + 31593719 = 31593846
157 + 31593689 = 31593846
199 + 31593647 = 31593846

Showing the first eight; more decompositions exist.
