Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722668, here are decompositions:

7 + 8722661 = 8722668
37 + 8722631 = 8722668
47 + 8722621 = 8722668
61 + 8722607 = 8722668
127 + 8722541 = 8722668
151 + 8722517 = 8722668
191 + 8722477 = 8722668
197 + 8722471 = 8722668

Showing the first eight; more decompositions exist.
