Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55170, here are decompositions:

7 + 55163 = 55170
23 + 55147 = 55170
43 + 55127 = 55170
53 + 55117 = 55170
61 + 55109 = 55170
67 + 55103 = 55170
97 + 55073 = 55170
109 + 55061 = 55170

Showing the first eight; more decompositions exist.
