Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722964, here are decompositions:

73 + 8722891 = 8722964
487 + 8722477 = 8722964
541 + 8722423 = 8722964
571 + 8722393 = 8722964
631 + 8722333 = 8722964
661 + 8722303 = 8722964
673 + 8722291 = 8722964
727 + 8722237 = 8722964

Showing the first eight; more decompositions exist.
