Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622990, here are decompositions:

7 + 8622983 = 8622990
17 + 8622973 = 8622990
31 + 8622959 = 8622990
67 + 8622923 = 8622990
107 + 8622883 = 8622990
113 + 8622877 = 8622990
137 + 8622853 = 8622990
149 + 8622841 = 8622990

Showing the first eight; more decompositions exist.
