Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55998, here are decompositions:

11 + 55987 = 55998
31 + 55967 = 55998
67 + 55931 = 55998
71 + 55927 = 55998
97 + 55901 = 55998
101 + 55897 = 55998
109 + 55889 = 55998
127 + 55871 = 55998

Showing the first eight; more decompositions exist.
