Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722766, here are decompositions:

163 + 8722603 = 8722766
307 + 8722459 = 8722766
337 + 8722429 = 8722766
373 + 8722393 = 8722766
433 + 8722333 = 8722766
463 + 8722303 = 8722766
643 + 8722123 = 8722766
673 + 8722093 = 8722766

Showing the first eight; more decompositions exist.
