Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722806, here are decompositions:

7 + 8722799 = 8722806
17 + 8722789 = 8722806
67 + 8722739 = 8722806
163 + 8722643 = 8722806
193 + 8722613 = 8722806
199 + 8722607 = 8722806
307 + 8722499 = 8722806
347 + 8722459 = 8722806

Showing the first eight; more decompositions exist.
