Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66256, here are decompositions:
- 17 + 66239 = 66256
- 83 + 66173 = 66256
- 149 + 66107 = 66256
- 167 + 66089 = 66256
- 173 + 66083 = 66256
- 227 + 66029 = 66256
- 263 + 65993 = 66256
- 293 + 65963 = 66256
Showing the first eight; more decompositions exist.
