Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626824, here are decompositions:

5 + 8626819 = 8626824
13 + 8626811 = 8626824
23 + 8626801 = 8626824
47 + 8626777 = 8626824
61 + 8626763 = 8626824
127 + 8626697 = 8626824
181 + 8626643 = 8626824
211 + 8626613 = 8626824

Showing the first eight; more decompositions exist.
