Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66306, here are decompositions:
- 5 + 66301 = 66306
- 13 + 66293 = 66306
- 67 + 66239 = 66306
- 127 + 66179 = 66306
- 137 + 66169 = 66306
- 197 + 66109 = 66306
- 199 + 66107 = 66306
- 223 + 66083 = 66306
Showing the first eight; more decompositions exist.
