Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55972, here are decompositions:

5 + 55967 = 55972
23 + 55949 = 55972
41 + 55931 = 55972
71 + 55901 = 55972
83 + 55889 = 55972
101 + 55871 = 55972
149 + 55823 = 55972
173 + 55799 = 55972

Showing the first eight; more decompositions exist.
