Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593610, here are decompositions:

3 + 31593607 = 31593610
47 + 31593563 = 31593610
107 + 31593503 = 31593610
131 + 31593479 = 31593610
149 + 31593461 = 31593610
173 + 31593437 = 31593610
233 + 31593377 = 31593610
311 + 31593299 = 31593610

Showing the first eight; more decompositions exist.
