Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533624, here are decompositions:

11 + 31533613 = 31533624
13 + 31533611 = 31533624
37 + 31533587 = 31533624
43 + 31533581 = 31533624
53 + 31533571 = 31533624
61 + 31533563 = 31533624
107 + 31533517 = 31533624
113 + 31533511 = 31533624

Showing the first eight; more decompositions exist.
