Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124942, here are decompositions:
- 23 + 124919 = 124942
- 89 + 124853 = 124942
- 149 + 124793 = 124942
- 173 + 124769 = 124942
- 239 + 124703 = 124942
- 263 + 124679 = 124942
- 269 + 124673 = 124942
- 401 + 124541 = 124942
Showing the first eight; more decompositions exist.
