Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668742, here are decompositions:
- 3 + 8668739 = 8668742
- 31 + 8668711 = 8668742
- 193 + 8668549 = 8668742
- 223 + 8668519 = 8668742
- 241 + 8668501 = 8668742
- 283 + 8668459 = 8668742
- 373 + 8668369 = 8668742
- 463 + 8668279 = 8668742
Showing the first eight; more decompositions exist.
