Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486986, here are decompositions:

139 + 33486847 = 33486986
157 + 33486829 = 33486986
223 + 33486763 = 33486986
283 + 33486703 = 33486986
409 + 33486577 = 33486986
439 + 33486547 = 33486986
787 + 33486199 = 33486986
823 + 33486163 = 33486986

Showing the first eight; more decompositions exist.
