Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523942, here are decompositions:
- 5 + 523937 = 523942
- 113 + 523829 = 523942
- 149 + 523793 = 523942
- 179 + 523763 = 523942
- 269 + 523673 = 523942
- 311 + 523631 = 523942
- 389 + 523553 = 523942
- 401 + 523541 = 523942
Showing the first eight; more decompositions exist.
