Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626806, here are decompositions:

5 + 8626801 = 8626806
29 + 8626777 = 8626806
43 + 8626763 = 8626806
59 + 8626747 = 8626806
73 + 8626733 = 8626806
107 + 8626699 = 8626806
109 + 8626697 = 8626806
137 + 8626669 = 8626806

Showing the first eight; more decompositions exist.
