Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629866, here are decompositions:

19 + 8629847 = 8629866
43 + 8629823 = 8629866
53 + 8629813 = 8629866
103 + 8629763 = 8629866
127 + 8629739 = 8629866
229 + 8629637 = 8629866
269 + 8629597 = 8629866
283 + 8629583 = 8629866

Showing the first eight; more decompositions exist.
