Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486780, here are decompositions:

11 + 33486769 = 33486780
13 + 33486767 = 33486780
17 + 33486763 = 33486780
29 + 33486751 = 33486780
31 + 33486749 = 33486780
83 + 33486697 = 33486780
109 + 33486671 = 33486780
139 + 33486641 = 33486780

Showing the first eight; more decompositions exist.
