Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486672, here are decompositions:

31 + 33486641 = 33486672
61 + 33486611 = 33486672
199 + 33486473 = 33486672
269 + 33486403 = 33486672
281 + 33486391 = 33486672
283 + 33486389 = 33486672
311 + 33486361 = 33486672
353 + 33486319 = 33486672

Showing the first eight; more decompositions exist.
