Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533564, here are decompositions:

17 + 31533547 = 31533564
31 + 31533533 = 31533564
47 + 31533517 = 31533564
53 + 31533511 = 31533564
67 + 31533497 = 31533564
103 + 31533461 = 31533564
113 + 31533451 = 31533564
151 + 31533413 = 31533564

Showing the first eight; more decompositions exist.
