Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55980, here are decompositions:
- 13 + 55967 = 55980
- 31 + 55949 = 55980
- 47 + 55933 = 55980
- 53 + 55927 = 55980
- 59 + 55921 = 55980
- 79 + 55901 = 55980
- 83 + 55897 = 55980
- 109 + 55871 = 55980
Showing the first eight; more decompositions exist.
