Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668668, here are decompositions:
- 31 + 8668637 = 8668668
- 59 + 8668609 = 8668668
- 97 + 8668571 = 8668668
- 149 + 8668519 = 8668668
- 167 + 8668501 = 8668668
- 179 + 8668489 = 8668668
- 311 + 8668357 = 8668668
- 367 + 8668301 = 8668668
Showing the first eight; more decompositions exist.
