Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55986, here are decompositions:

19 + 55967 = 55986
37 + 55949 = 55986
53 + 55933 = 55986
59 + 55927 = 55986
83 + 55903 = 55986
89 + 55897 = 55986
97 + 55889 = 55986
137 + 55849 = 55986

Showing the first eight; more decompositions exist.
