Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84648, here are decompositions:
- 17 + 84631 = 84648
- 19 + 84629 = 84648
- 59 + 84589 = 84648
- 89 + 84559 = 84648
- 97 + 84551 = 84648
- 127 + 84521 = 84648
- 139 + 84509 = 84648
- 149 + 84499 = 84648
Showing the first eight; more decompositions exist.
