Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513388, here are decompositions:

107 + 33513281 = 33513388
131 + 33513257 = 33513388
191 + 33513197 = 33513388
281 + 33513107 = 33513388
401 + 33512987 = 33513388
449 + 33512939 = 33513388
641 + 33512747 = 33513388
809 + 33512579 = 33513388

Showing the first eight; more decompositions exist.
