Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121792, here are decompositions:
- 3 + 121789 = 121792
- 5 + 121787 = 121792
- 29 + 121763 = 121792
- 71 + 121721 = 121792
- 131 + 121661 = 121792
- 233 + 121559 = 121792
- 239 + 121553 = 121792
- 269 + 121523 = 121792
Showing the first eight; more decompositions exist.
