Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688704, here are decompositions:
- 7 + 8688697 = 8688704
- 97 + 8688607 = 8688704
- 103 + 8688601 = 8688704
- 127 + 8688577 = 8688704
- 151 + 8688553 = 8688704
- 307 + 8688397 = 8688704
- 421 + 8688283 = 8688704
- 433 + 8688271 = 8688704
Showing the first eight; more decompositions exist.
