Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55180, here are decompositions:

17 + 55163 = 55180
53 + 55127 = 55180
71 + 55109 = 55180
101 + 55079 = 55180
107 + 55073 = 55180
131 + 55049 = 55180
179 + 55001 = 55180
197 + 54983 = 55180

Showing the first eight; more decompositions exist.
