Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651130, here are decompositions:

11 + 8651119 = 8651130
13 + 8651117 = 8651130
67 + 8651063 = 8651130
79 + 8651051 = 8651130
83 + 8651047 = 8651130
113 + 8651017 = 8651130
149 + 8650981 = 8651130
151 + 8650979 = 8651130

Showing the first eight; more decompositions exist.
