Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55146, here are decompositions:

19 + 55127 = 55146
29 + 55117 = 55146
37 + 55109 = 55146
43 + 55103 = 55146
67 + 55079 = 55146
73 + 55073 = 55146
89 + 55057 = 55146
97 + 55049 = 55146

Showing the first eight; more decompositions exist.
