Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66286, here are decompositions:
- 47 + 66239 = 66286
- 107 + 66179 = 66286
- 113 + 66173 = 66286
- 149 + 66137 = 66286
- 179 + 66107 = 66286
- 197 + 66089 = 66286
- 239 + 66047 = 66286
- 257 + 66029 = 66286
Showing the first eight; more decompositions exist.
