Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84666, here are decompositions:
- 7 + 84659 = 84666
- 13 + 84653 = 84666
- 17 + 84649 = 84666
- 37 + 84629 = 84666
- 107 + 84559 = 84666
- 157 + 84509 = 84666
- 163 + 84503 = 84666
- 167 + 84499 = 84666
Showing the first eight; more decompositions exist.
