Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121696, here are decompositions:
- 59 + 121637 = 121696
- 89 + 121607 = 121696
- 137 + 121559 = 121696
- 149 + 121547 = 121696
- 173 + 121523 = 121696
- 227 + 121469 = 121696
- 257 + 121439 = 121696
- 293 + 121403 = 121696
Showing the first eight; more decompositions exist.
