Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42942, here are decompositions:
- 5 + 42937 = 42942
- 13 + 42929 = 42942
- 19 + 42923 = 42942
- 41 + 42901 = 42942
- 43 + 42899 = 42942
- 79 + 42863 = 42942
- 83 + 42859 = 42942
- 89 + 42853 = 42942
Showing the first eight; more decompositions exist.
