Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55894, here are decompositions:

5 + 55889 = 55894
23 + 55871 = 55894
71 + 55823 = 55894
101 + 55793 = 55894
107 + 55787 = 55894
131 + 55763 = 55894
173 + 55721 = 55894
197 + 55697 = 55894

Showing the first eight; more decompositions exist.
