Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66966, here are decompositions:

7 + 66959 = 66966
17 + 66949 = 66966
19 + 66947 = 66966
23 + 66943 = 66966
43 + 66923 = 66966
47 + 66919 = 66966
83 + 66883 = 66966
89 + 66877 = 66966

Showing the first eight; more decompositions exist.
