Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55942, here are decompositions:

11 + 55931 = 55942
41 + 55901 = 55942
53 + 55889 = 55942
71 + 55871 = 55942
113 + 55829 = 55942
149 + 55793 = 55942
179 + 55763 = 55942
251 + 55691 = 55942

Showing the first eight; more decompositions exist.
