Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721710, here are decompositions:

37 + 8721673 = 8721710
43 + 8721667 = 8721710
79 + 8721631 = 8721710
103 + 8721607 = 8721710
199 + 8721511 = 8721710
211 + 8721499 = 8721710
223 + 8721487 = 8721710
229 + 8721481 = 8721710

Showing the first eight; more decompositions exist.
