Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593618, here are decompositions:

5 + 31593613 = 31593618
11 + 31593607 = 31593618
29 + 31593589 = 31593618
47 + 31593571 = 31593618
101 + 31593517 = 31593618
107 + 31593511 = 31593618
127 + 31593491 = 31593618
139 + 31593479 = 31593618

Showing the first eight; more decompositions exist.
