Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622728, here are decompositions:

7 + 8622721 = 8622728
151 + 8622577 = 8622728
199 + 8622529 = 8622728
229 + 8622499 = 8622728
241 + 8622487 = 8622728
307 + 8622421 = 8622728
337 + 8622391 = 8622728
349 + 8622379 = 8622728

Showing the first eight; more decompositions exist.
