Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55988, here are decompositions:

61 + 55927 = 55988
67 + 55921 = 55988
139 + 55849 = 55988
151 + 55837 = 55988
181 + 55807 = 55988
271 + 55717 = 55988
277 + 55711 = 55988
307 + 55681 = 55988

Showing the first eight; more decompositions exist.
