Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486942, here are decompositions:

79 + 33486863 = 33486942
101 + 33486841 = 33486942
109 + 33486833 = 33486942
113 + 33486829 = 33486942
173 + 33486769 = 33486942
179 + 33486763 = 33486942
191 + 33486751 = 33486942
193 + 33486749 = 33486942

Showing the first eight; more decompositions exist.
