Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55918, here are decompositions:

17 + 55901 = 55918
29 + 55889 = 55918
47 + 55871 = 55918
89 + 55829 = 55918
101 + 55817 = 55918
131 + 55787 = 55918
197 + 55721 = 55918
227 + 55691 = 55918

Showing the first eight; more decompositions exist.
