Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513778, here are decompositions:

17 + 33513761 = 33513778
47 + 33513731 = 33513778
71 + 33513707 = 33513778
149 + 33513629 = 33513778
167 + 33513611 = 33513778
197 + 33513581 = 33513778
227 + 33513551 = 33513778
239 + 33513539 = 33513778

Showing the first eight; more decompositions exist.
