Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624828, here are decompositions:

7 + 8624821 = 8624828
151 + 8624677 = 8624828
211 + 8624617 = 8624828
229 + 8624599 = 8624828
379 + 8624449 = 8624828
577 + 8624251 = 8624828
607 + 8624221 = 8624828
691 + 8624137 = 8624828

Showing the first eight; more decompositions exist.
