Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55900, here are decompositions:

3 + 55897 = 55900
11 + 55889 = 55900
29 + 55871 = 55900
71 + 55829 = 55900
83 + 55817 = 55900
101 + 55799 = 55900
107 + 55793 = 55900
113 + 55787 = 55900

Showing the first eight; more decompositions exist.
