Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617824, here are decompositions:
- 37 + 8617787 = 8617824
- 71 + 8617753 = 8617824
- 197 + 8617627 = 8617824
- 263 + 8617561 = 8617824
- 277 + 8617547 = 8617824
- 311 + 8617513 = 8617824
- 433 + 8617391 = 8617824
- 443 + 8617381 = 8617824
Showing the first eight; more decompositions exist.
