Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622028, here are decompositions:

5 + 8622023 = 8622028
11 + 8622017 = 8622028
17 + 8622011 = 8622028
89 + 8621939 = 8622028
101 + 8621927 = 8622028
131 + 8621897 = 8622028
167 + 8621861 = 8622028
197 + 8621831 = 8622028

Showing the first eight; more decompositions exist.
