Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662166, here are decompositions:

13 + 8662153 = 8662166
109 + 8662057 = 8662166
157 + 8662009 = 8662166
223 + 8661943 = 8662166
277 + 8661889 = 8662166
283 + 8661883 = 8662166
367 + 8661799 = 8662166
397 + 8661769 = 8662166

Showing the first eight; more decompositions exist.
