Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55880, here are decompositions:

31 + 55849 = 55880
37 + 55843 = 55880
43 + 55837 = 55880
61 + 55819 = 55880
67 + 55813 = 55880
73 + 55807 = 55880
163 + 55717 = 55880
199 + 55681 = 55880

Showing the first eight; more decompositions exist.
