Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147930, here are decompositions:

11 + 147919 = 147930
67 + 147863 = 147930
71 + 147859 = 147930
103 + 147827 = 147930
131 + 147799 = 147930
137 + 147793 = 147930
151 + 147779 = 147930
157 + 147773 = 147930

Showing the first eight; more decompositions exist.
