Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722662, here are decompositions:

19 + 8722643 = 8722662
31 + 8722631 = 8722662
41 + 8722621 = 8722662
59 + 8722603 = 8722662
163 + 8722499 = 8722662
191 + 8722471 = 8722662
233 + 8722429 = 8722662
239 + 8722423 = 8722662

Showing the first eight; more decompositions exist.
