Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13266, here are decompositions:
- 7 + 13259 = 13266
- 17 + 13249 = 13266
- 37 + 13229 = 13266
- 47 + 13219 = 13266
- 79 + 13187 = 13266
- 83 + 13183 = 13266
- 89 + 13177 = 13266
- 103 + 13163 = 13266
Showing the first eight; more decompositions exist.
