Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55910, here are decompositions:

7 + 55903 = 55910
13 + 55897 = 55910
61 + 55849 = 55910
67 + 55843 = 55910
73 + 55837 = 55910
97 + 55813 = 55910
103 + 55807 = 55910
193 + 55717 = 55910

Showing the first eight; more decompositions exist.
