Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593516, here are decompositions:

5 + 31593511 = 31593516
13 + 31593503 = 31593516
37 + 31593479 = 31593516
79 + 31593437 = 31593516
127 + 31593389 = 31593516
139 + 31593377 = 31593516
173 + 31593343 = 31593516
263 + 31593253 = 31593516

Showing the first eight; more decompositions exist.
