Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486786, here are decompositions:

17 + 33486769 = 33486786
19 + 33486767 = 33486786
23 + 33486763 = 33486786
37 + 33486749 = 33486786
83 + 33486703 = 33486786
89 + 33486697 = 33486786
163 + 33486623 = 33486786
199 + 33486587 = 33486786

Showing the first eight; more decompositions exist.
