Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722970, here are decompositions:

79 + 8722891 = 8722970
181 + 8722789 = 8722970
349 + 8722621 = 8722970
367 + 8722603 = 8722970
499 + 8722471 = 8722970
523 + 8722447 = 8722970
541 + 8722429 = 8722970
547 + 8722423 = 8722970

Showing the first eight; more decompositions exist.
