Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486912, here are decompositions:

71 + 33486841 = 33486912
79 + 33486833 = 33486912
83 + 33486829 = 33486912
113 + 33486799 = 33486912
149 + 33486763 = 33486912
163 + 33486749 = 33486912
181 + 33486731 = 33486912
241 + 33486671 = 33486912

Showing the first eight; more decompositions exist.
