Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666606, here are decompositions:

73 + 8666533 = 8666606
127 + 8666479 = 8666606
163 + 8666443 = 8666606
283 + 8666323 = 8666606
337 + 8666269 = 8666606
433 + 8666173 = 8666606
439 + 8666167 = 8666606
547 + 8666059 = 8666606

Showing the first eight; more decompositions exist.
