Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687672, here are decompositions:
- 3 + 8687669 = 8687672
- 13 + 8687659 = 8687672
- 31 + 8687641 = 8687672
- 73 + 8687599 = 8687672
- 151 + 8687521 = 8687672
- 193 + 8687479 = 8687672
- 211 + 8687461 = 8687672
- 271 + 8687401 = 8687672
Showing the first eight; more decompositions exist.
