Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55966, here are decompositions:

17 + 55949 = 55966
137 + 55829 = 55966
149 + 55817 = 55966
167 + 55799 = 55966
173 + 55793 = 55966
179 + 55787 = 55966
233 + 55733 = 55966
269 + 55697 = 55966

Showing the first eight; more decompositions exist.
