Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66340, here are decompositions:
- 3 + 66337 = 66340
- 47 + 66293 = 66340
- 101 + 66239 = 66340
- 149 + 66191 = 66340
- 167 + 66173 = 66340
- 179 + 66161 = 66340
- 233 + 66107 = 66340
- 251 + 66089 = 66340
Showing the first eight; more decompositions exist.
