Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104742, here are decompositions:
- 13 + 104729 = 104742
- 19 + 104723 = 104742
- 31 + 104711 = 104742
- 41 + 104701 = 104742
- 59 + 104683 = 104742
- 61 + 104681 = 104742
- 83 + 104659 = 104742
- 103 + 104639 = 104742
Showing the first eight; more decompositions exist.
