Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84664, here are decompositions:
- 5 + 84659 = 84664
- 11 + 84653 = 84664
- 113 + 84551 = 84664
- 131 + 84533 = 84664
- 197 + 84467 = 84664
- 227 + 84437 = 84664
- 233 + 84431 = 84664
- 257 + 84407 = 84664
Showing the first eight; more decompositions exist.
