Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643166, here are decompositions:

17 + 8643149 = 8643166
23 + 8643143 = 8643166
29 + 8643137 = 8643166
83 + 8643083 = 8643166
89 + 8643077 = 8643166
107 + 8643059 = 8643166
113 + 8643053 = 8643166
227 + 8642939 = 8643166

Showing the first eight; more decompositions exist.
