Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84742, here are decompositions:
- 5 + 84737 = 84742
- 11 + 84731 = 84742
- 23 + 84719 = 84742
- 29 + 84713 = 84742
- 41 + 84701 = 84742
- 83 + 84659 = 84742
- 89 + 84653 = 84742
- 113 + 84629 = 84742
Showing the first eight; more decompositions exist.
