Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626830, here are decompositions:

7 + 8626823 = 8626830
11 + 8626819 = 8626830
19 + 8626811 = 8626830
29 + 8626801 = 8626830
53 + 8626777 = 8626830
67 + 8626763 = 8626830
83 + 8626747 = 8626830
97 + 8626733 = 8626830

Showing the first eight; more decompositions exist.
