Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68742, here are decompositions:
- 5 + 68737 = 68742
- 13 + 68729 = 68742
- 29 + 68713 = 68742
- 31 + 68711 = 68742
- 43 + 68699 = 68742
- 59 + 68683 = 68742
- 73 + 68669 = 68742
- 83 + 68659 = 68742
Showing the first eight; more decompositions exist.
