Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66250, here are decompositions:
- 11 + 66239 = 66250
- 29 + 66221 = 66250
- 59 + 66191 = 66250
- 71 + 66179 = 66250
- 89 + 66161 = 66250
- 113 + 66137 = 66250
- 167 + 66083 = 66250
- 179 + 66071 = 66250
Showing the first eight; more decompositions exist.
