Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671040, here are decompositions:
- 31 + 8671009 = 8671040
- 43 + 8670997 = 8671040
- 97 + 8670943 = 8671040
- 229 + 8670811 = 8671040
- 331 + 8670709 = 8671040
- 337 + 8670703 = 8671040
- 373 + 8670667 = 8671040
- 421 + 8670619 = 8671040
Showing the first eight; more decompositions exist.
