Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486666, here are decompositions:

43 + 33486623 = 33486666
79 + 33486587 = 33486666
89 + 33486577 = 33486666
193 + 33486473 = 33486666
197 + 33486469 = 33486666
263 + 33486403 = 33486666
277 + 33486389 = 33486666
313 + 33486353 = 33486666

Showing the first eight; more decompositions exist.
