Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664138, here are decompositions:

29 + 8664109 = 8664138
31 + 8664107 = 8664138
101 + 8664037 = 8664138
151 + 8663987 = 8664138
179 + 8663959 = 8664138
239 + 8663899 = 8664138
269 + 8663869 = 8664138
277 + 8663861 = 8664138

Showing the first eight; more decompositions exist.
