Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513618, here are decompositions:

7 + 33513611 = 33513618
37 + 33513581 = 33513618
59 + 33513559 = 33513618
67 + 33513551 = 33513618
71 + 33513547 = 33513618
79 + 33513539 = 33513618
109 + 33513509 = 33513618
139 + 33513479 = 33513618

Showing the first eight; more decompositions exist.
