Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486420, here are decompositions:

17 + 33486403 = 33486420
29 + 33486391 = 33486420
31 + 33486389 = 33486420
59 + 33486361 = 33486420
67 + 33486353 = 33486420
83 + 33486337 = 33486420
89 + 33486331 = 33486420
101 + 33486319 = 33486420

Showing the first eight; more decompositions exist.
