Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121450, here are decompositions:
- 3 + 121447 = 121450
- 11 + 121439 = 121450
- 29 + 121421 = 121450
- 47 + 121403 = 121450
- 71 + 121379 = 121450
- 83 + 121367 = 121450
- 101 + 121349 = 121450
- 107 + 121343 = 121450
Showing the first eight; more decompositions exist.
