Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533824, here are decompositions:

61 + 31533763 = 31533824
103 + 31533721 = 31533824
163 + 31533661 = 31533824
193 + 31533631 = 31533824
211 + 31533613 = 31533824
277 + 31533547 = 31533824
307 + 31533517 = 31533824
313 + 31533511 = 31533824

Showing the first eight; more decompositions exist.
