Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486820, here are decompositions:

53 + 33486767 = 33486820
71 + 33486749 = 33486820
89 + 33486731 = 33486820
149 + 33486671 = 33486820
179 + 33486641 = 33486820
197 + 33486623 = 33486820
233 + 33486587 = 33486820
239 + 33486581 = 33486820

Showing the first eight; more decompositions exist.
