Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608, here are decompositions:
- 11 + 8597 = 8608
- 71 + 8537 = 8608
- 107 + 8501 = 8608
- 179 + 8429 = 8608
- 239 + 8369 = 8608
- 311 + 8297 = 8608
- 317 + 8291 = 8608
- 389 + 8219 = 8608
Showing the first eight; more decompositions exist.
