Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55918, here are decompositions:
- 17 + 55901 = 55918
- 29 + 55889 = 55918
- 47 + 55871 = 55918
- 89 + 55829 = 55918
- 101 + 55817 = 55918
- 131 + 55787 = 55918
- 197 + 55721 = 55918
- 227 + 55691 = 55918
Showing the first eight; more decompositions exist.
