Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66330, here are decompositions:
- 29 + 66301 = 66330
- 37 + 66293 = 66330
- 59 + 66271 = 66330
- 109 + 66221 = 66330
- 139 + 66191 = 66330
- 151 + 66179 = 66330
- 157 + 66173 = 66330
- 193 + 66137 = 66330
Showing the first eight; more decompositions exist.
