Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18966, here are decompositions:

7 + 18959 = 18966
19 + 18947 = 18966
47 + 18919 = 18966
53 + 18913 = 18966
67 + 18899 = 18966
97 + 18869 = 18966
107 + 18859 = 18966
127 + 18839 = 18966

Showing the first eight; more decompositions exist.
