Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55086, here are decompositions:

7 + 55079 = 55086
13 + 55073 = 55086
29 + 55057 = 55086
37 + 55049 = 55086
103 + 54983 = 55086
107 + 54979 = 55086
113 + 54973 = 55086
127 + 54959 = 55086

Showing the first eight; more decompositions exist.
