Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84672, here are decompositions:
- 13 + 84659 = 84672
- 19 + 84653 = 84672
- 23 + 84649 = 84672
- 41 + 84631 = 84672
- 43 + 84629 = 84672
- 83 + 84589 = 84672
- 113 + 84559 = 84672
- 139 + 84533 = 84672
Showing the first eight; more decompositions exist.
