Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121726, here are decompositions:
- 5 + 121721 = 121726
- 29 + 121697 = 121726
- 89 + 121637 = 121726
- 149 + 121577 = 121726
- 167 + 121559 = 121726
- 173 + 121553 = 121726
- 179 + 121547 = 121726
- 233 + 121493 = 121726
Showing the first eight; more decompositions exist.
