Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722976, here are decompositions:

7 + 8722969 = 8722976
373 + 8722603 = 8722976
499 + 8722477 = 8722976
547 + 8722429 = 8722976
643 + 8722333 = 8722976
673 + 8722303 = 8722976
739 + 8722237 = 8722976
853 + 8722123 = 8722976

Showing the first eight; more decompositions exist.
