Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486142, here are decompositions:

3 + 33486139 = 33486142
23 + 33486119 = 33486142
71 + 33486071 = 33486142
101 + 33486041 = 33486142
233 + 33485909 = 33486142
251 + 33485891 = 33486142
269 + 33485873 = 33486142
311 + 33485831 = 33486142

Showing the first eight; more decompositions exist.
