Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55890, here are decompositions:

19 + 55871 = 55890
41 + 55849 = 55890
47 + 55843 = 55890
53 + 55837 = 55890
61 + 55829 = 55890
67 + 55823 = 55890
71 + 55819 = 55890
73 + 55817 = 55890

Showing the first eight; more decompositions exist.
