Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486980, here are decompositions:

139 + 33486841 = 33486980
151 + 33486829 = 33486980
181 + 33486799 = 33486980
211 + 33486769 = 33486980
229 + 33486751 = 33486980
277 + 33486703 = 33486980
283 + 33486697 = 33486980
433 + 33486547 = 33486980

Showing the first eight; more decompositions exist.
