Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55866, here are decompositions:

17 + 55849 = 55866
23 + 55843 = 55866
29 + 55837 = 55866
37 + 55829 = 55866
43 + 55823 = 55866
47 + 55819 = 55866
53 + 55813 = 55866
59 + 55807 = 55866

Showing the first eight; more decompositions exist.
