Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533584, here are decompositions:

3 + 31533581 = 31533584
13 + 31533571 = 31533584
37 + 31533547 = 31533584
67 + 31533517 = 31533584
73 + 31533511 = 31533584
241 + 31533343 = 31533584
457 + 31533127 = 31533584
487 + 31533097 = 31533584

Showing the first eight; more decompositions exist.
