Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121112, here are decompositions:
- 31 + 121081 = 121112
- 73 + 121039 = 121112
- 193 + 120919 = 121112
- 223 + 120889 = 121112
- 241 + 120871 = 121112
- 283 + 120829 = 121112
- 349 + 120763 = 121112
- 373 + 120739 = 121112
Showing the first eight; more decompositions exist.
