Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622740, here are decompositions:

19 + 8622721 = 8622740
163 + 8622577 = 8622740
211 + 8622529 = 8622740
229 + 8622511 = 8622740
241 + 8622499 = 8622740
271 + 8622469 = 8622740
277 + 8622463 = 8622740
349 + 8622391 = 8622740

Showing the first eight; more decompositions exist.
