Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533516, here are decompositions:

5 + 31533511 = 31533516
17 + 31533499 = 31533516
19 + 31533497 = 31533516
67 + 31533449 = 31533516
103 + 31533413 = 31533516
107 + 31533409 = 31533516
127 + 31533389 = 31533516
137 + 31533379 = 31533516

Showing the first eight; more decompositions exist.
