Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55940, here are decompositions:

7 + 55933 = 55940
13 + 55927 = 55940
19 + 55921 = 55940
37 + 55903 = 55940
43 + 55897 = 55940
97 + 55843 = 55940
103 + 55837 = 55940
127 + 55813 = 55940

Showing the first eight; more decompositions exist.
