Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593786, here are decompositions:

19 + 31593767 = 31593786
23 + 31593763 = 31593786
67 + 31593719 = 31593786
83 + 31593703 = 31593786
97 + 31593689 = 31593786
139 + 31593647 = 31593786
157 + 31593629 = 31593786
173 + 31593613 = 31593786

Showing the first eight; more decompositions exist.
