Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626864, here are decompositions:

3 + 8626861 = 8626864
17 + 8626847 = 8626864
23 + 8626841 = 8626864
41 + 8626823 = 8626864
53 + 8626811 = 8626864
101 + 8626763 = 8626864
131 + 8626733 = 8626864
167 + 8626697 = 8626864

Showing the first eight; more decompositions exist.
