Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486144, here are decompositions:

5 + 33486139 = 33486144
67 + 33486077 = 33486144
73 + 33486071 = 33486144
103 + 33486041 = 33486144
113 + 33486031 = 33486144
137 + 33486007 = 33486144
257 + 33485887 = 33486144
271 + 33485873 = 33486144

Showing the first eight; more decompositions exist.
