Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66160, here are decompositions:
- 23 + 66137 = 66160
- 53 + 66107 = 66160
- 71 + 66089 = 66160
- 89 + 66071 = 66160
- 113 + 66047 = 66160
- 131 + 66029 = 66160
- 167 + 65993 = 66160
- 179 + 65981 = 66160
Showing the first eight; more decompositions exist.
