Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66118, here are decompositions:
- 11 + 66107 = 66118
- 29 + 66089 = 66118
- 47 + 66071 = 66118
- 71 + 66047 = 66118
- 89 + 66029 = 66118
- 137 + 65981 = 66118
- 167 + 65951 = 66118
- 191 + 65927 = 66118
Showing the first eight; more decompositions exist.
