Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593766, here are decompositions:

3 + 31593763 = 31593766
47 + 31593719 = 31593766
137 + 31593629 = 31593766
233 + 31593533 = 31593766
263 + 31593503 = 31593766
389 + 31593377 = 31593766
467 + 31593299 = 31593766
569 + 31593197 = 31593766

Showing the first eight; more decompositions exist.
