Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55870, here are decompositions:

41 + 55829 = 55870
47 + 55823 = 55870
53 + 55817 = 55870
71 + 55799 = 55870
83 + 55787 = 55870
107 + 55763 = 55870
137 + 55733 = 55870
149 + 55721 = 55870

Showing the first eight; more decompositions exist.
