Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622828, here are decompositions:

17 + 8622811 = 8622828
47 + 8622781 = 8622828
61 + 8622767 = 8622828
107 + 8622721 = 8622828
251 + 8622577 = 8622828
307 + 8622521 = 8622828
317 + 8622511 = 8622828
337 + 8622491 = 8622828

Showing the first eight; more decompositions exist.
