Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55882, here are decompositions:

11 + 55871 = 55882
53 + 55829 = 55882
59 + 55823 = 55882
83 + 55799 = 55882
89 + 55793 = 55882
149 + 55733 = 55882
191 + 55691 = 55882
251 + 55631 = 55882

Showing the first eight; more decompositions exist.
