Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533924, here are decompositions:

5 + 31533919 = 31533924
13 + 31533911 = 31533924
53 + 31533871 = 31533924
101 + 31533823 = 31533924
151 + 31533773 = 31533924
263 + 31533661 = 31533924
283 + 31533641 = 31533924
293 + 31533631 = 31533924

Showing the first eight; more decompositions exist.
