Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55128, here are decompositions:

11 + 55117 = 55128
19 + 55109 = 55128
67 + 55061 = 55128
71 + 55057 = 55128
79 + 55049 = 55128
107 + 55021 = 55128
127 + 55001 = 55128
149 + 54979 = 55128

Showing the first eight; more decompositions exist.
