Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622918, here are decompositions:

41 + 8622877 = 8622918
47 + 8622871 = 8622918
61 + 8622857 = 8622918
71 + 8622847 = 8622918
107 + 8622811 = 8622918
137 + 8622781 = 8622918
151 + 8622767 = 8622918
197 + 8622721 = 8622918

Showing the first eight; more decompositions exist.
