Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687948, here are decompositions:
- 19 + 8687929 = 8687948
- 37 + 8687911 = 8687948
- 67 + 8687881 = 8687948
- 151 + 8687797 = 8687948
- 277 + 8687671 = 8687948
- 307 + 8687641 = 8687948
- 349 + 8687599 = 8687948
- 487 + 8687461 = 8687948
Showing the first eight; more decompositions exist.
