Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668470, here are decompositions:
- 11 + 8668459 = 8668470
- 47 + 8668423 = 8668470
- 67 + 8668403 = 8668470
- 89 + 8668381 = 8668470
- 101 + 8668369 = 8668470
- 103 + 8668367 = 8668470
- 113 + 8668357 = 8668470
- 191 + 8668279 = 8668470
Showing the first eight; more decompositions exist.
