Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55978, here are decompositions:
- 11 + 55967 = 55978
- 29 + 55949 = 55978
- 47 + 55931 = 55978
- 89 + 55889 = 55978
- 107 + 55871 = 55978
- 149 + 55829 = 55978
- 179 + 55799 = 55978
- 191 + 55787 = 55978
Showing the first eight; more decompositions exist.
