Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593508, here are decompositions:

5 + 31593503 = 31593508
17 + 31593491 = 31593508
29 + 31593479 = 31593508
47 + 31593461 = 31593508
71 + 31593437 = 31593508
131 + 31593377 = 31593508
257 + 31593251 = 31593508
311 + 31593197 = 31593508

Showing the first eight; more decompositions exist.
