Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487012, here are decompositions:

59 + 33486953 = 33487012
71 + 33486941 = 33487012
149 + 33486863 = 33487012
179 + 33486833 = 33487012
263 + 33486749 = 33487012
281 + 33486731 = 33487012
389 + 33486623 = 33487012
401 + 33486611 = 33487012

Showing the first eight; more decompositions exist.
