Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722682, here are decompositions:

61 + 8722621 = 8722682
79 + 8722603 = 8722682
211 + 8722471 = 8722682
223 + 8722459 = 8722682
349 + 8722333 = 8722682
379 + 8722303 = 8722682
601 + 8722081 = 8722682
673 + 8722009 = 8722682

Showing the first eight; more decompositions exist.
