Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513786, here are decompositions:

73 + 33513713 = 33513786
79 + 33513707 = 33513786
113 + 33513673 = 33513786
127 + 33513659 = 33513786
157 + 33513629 = 33513786
227 + 33513559 = 33513786
239 + 33513547 = 33513786
277 + 33513509 = 33513786

Showing the first eight; more decompositions exist.
