Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121376, here are decompositions:
- 7 + 121369 = 121376
- 19 + 121357 = 121376
- 43 + 121333 = 121376
- 67 + 121309 = 121376
- 109 + 121267 = 121376
- 313 + 121063 = 121376
- 337 + 121039 = 121376
- 379 + 120997 = 121376
Showing the first eight; more decompositions exist.
