Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593522, here are decompositions:

5 + 31593517 = 31593522
11 + 31593511 = 31593522
19 + 31593503 = 31593522
31 + 31593491 = 31593522
43 + 31593479 = 31593522
61 + 31593461 = 31593522
131 + 31593391 = 31593522
179 + 31593343 = 31593522

Showing the first eight; more decompositions exist.
