Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121366, here are decompositions:
- 17 + 121349 = 121366
- 23 + 121343 = 121366
- 53 + 121313 = 121366
- 83 + 121283 = 121366
- 107 + 121259 = 121366
- 137 + 121229 = 121366
- 197 + 121169 = 121366
- 227 + 121139 = 121366
Showing the first eight; more decompositions exist.
