Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486240, here are decompositions:

17 + 33486223 = 33486240
41 + 33486199 = 33486240
43 + 33486197 = 33486240
61 + 33486179 = 33486240
83 + 33486157 = 33486240
97 + 33486143 = 33486240
101 + 33486139 = 33486240
131 + 33486109 = 33486240

Showing the first eight; more decompositions exist.
