Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618166, here are decompositions:

17 + 8618149 = 8618166
19 + 8618147 = 8618166
47 + 8618119 = 8618166
59 + 8618107 = 8618166
79 + 8618087 = 8618166
83 + 8618083 = 8618166
103 + 8618063 = 8618166
107 + 8618059 = 8618166

Showing the first eight; more decompositions exist.
