Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55120, here are decompositions:

3 + 55117 = 55120
11 + 55109 = 55120
17 + 55103 = 55120
41 + 55079 = 55120
47 + 55073 = 55120
59 + 55061 = 55120
71 + 55049 = 55120
137 + 54983 = 55120

Showing the first eight; more decompositions exist.
