Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84690, here are decompositions:
- 17 + 84673 = 84690
- 31 + 84659 = 84690
- 37 + 84653 = 84690
- 41 + 84649 = 84690
- 59 + 84631 = 84690
- 61 + 84629 = 84690
- 101 + 84589 = 84690
- 131 + 84559 = 84690
Showing the first eight; more decompositions exist.
