Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722010, here are decompositions:

13 + 8721997 = 8722010
97 + 8721913 = 8722010
103 + 8721907 = 8722010
127 + 8721883 = 8722010
337 + 8721673 = 8722010
379 + 8721631 = 8722010
499 + 8721511 = 8722010
523 + 8721487 = 8722010

Showing the first eight; more decompositions exist.
