Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84688, here are decompositions:
- 29 + 84659 = 84688
- 59 + 84629 = 84688
- 137 + 84551 = 84688
- 167 + 84521 = 84688
- 179 + 84509 = 84688
- 239 + 84449 = 84688
- 251 + 84437 = 84688
- 257 + 84431 = 84688
Showing the first eight; more decompositions exist.
