Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487816, here are decompositions:

3 + 33487813 = 33487816
59 + 33487757 = 33487816
83 + 33487733 = 33487816
503 + 33487313 = 33487816
569 + 33487247 = 33487816
653 + 33487163 = 33487816
863 + 33486953 = 33487816
953 + 33486863 = 33487816

Showing the first eight; more decompositions exist.
