Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668446, here are decompositions:
- 23 + 8668423 = 8668446
- 43 + 8668403 = 8668446
- 67 + 8668379 = 8668446
- 79 + 8668367 = 8668446
- 89 + 8668357 = 8668446
- 97 + 8668349 = 8668446
- 167 + 8668279 = 8668446
- 173 + 8668273 = 8668446
Showing the first eight; more decompositions exist.
