Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722118, here are decompositions:

19 + 8722099 = 8722118
37 + 8722081 = 8722118
109 + 8722009 = 8722118
211 + 8721907 = 8722118
241 + 8721877 = 8722118
487 + 8721631 = 8722118
577 + 8721541 = 8722118
607 + 8721511 = 8722118

Showing the first eight; more decompositions exist.
