Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486720, here are decompositions:

17 + 33486703 = 33486720
23 + 33486697 = 33486720
79 + 33486641 = 33486720
97 + 33486623 = 33486720
109 + 33486611 = 33486720
139 + 33486581 = 33486720
173 + 33486547 = 33486720
251 + 33486469 = 33486720

Showing the first eight; more decompositions exist.
