Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486810, here are decompositions:

11 + 33486799 = 33486810
41 + 33486769 = 33486810
43 + 33486767 = 33486810
47 + 33486763 = 33486810
59 + 33486751 = 33486810
61 + 33486749 = 33486810
79 + 33486731 = 33486810
107 + 33486703 = 33486810

Showing the first eight; more decompositions exist.
