Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66258, here are decompositions:
- 19 + 66239 = 66258
- 37 + 66221 = 66258
- 67 + 66191 = 66258
- 79 + 66179 = 66258
- 89 + 66169 = 66258
- 97 + 66161 = 66258
- 149 + 66109 = 66258
- 151 + 66107 = 66258
Showing the first eight; more decompositions exist.
