Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55906, here are decompositions:

3 + 55903 = 55906
5 + 55901 = 55906
17 + 55889 = 55906
83 + 55823 = 55906
89 + 55817 = 55906
107 + 55799 = 55906
113 + 55793 = 55906
173 + 55733 = 55906

Showing the first eight; more decompositions exist.
