Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42874, here are decompositions:
- 11 + 42863 = 42874
- 53 + 42821 = 42874
- 101 + 42773 = 42874
- 107 + 42767 = 42874
- 131 + 42743 = 42874
- 137 + 42737 = 42874
- 173 + 42701 = 42874
- 191 + 42683 = 42874
Showing the first eight; more decompositions exist.
