Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486490, here are decompositions:

17 + 33486473 = 33486490
101 + 33486389 = 33486490
137 + 33486353 = 33486490
227 + 33486263 = 33486490
239 + 33486251 = 33486490
293 + 33486197 = 33486490
311 + 33486179 = 33486490
347 + 33486143 = 33486490

Showing the first eight; more decompositions exist.
