Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147966, here are decompositions:

17 + 147949 = 147966
29 + 147937 = 147966
47 + 147919 = 147966
103 + 147863 = 147966
107 + 147859 = 147966
113 + 147853 = 147966
139 + 147827 = 147966
167 + 147799 = 147966

Showing the first eight; more decompositions exist.
