Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668642, here are decompositions:
- 5 + 8668637 = 8668642
- 29 + 8668613 = 8668642
- 71 + 8668571 = 8668642
- 89 + 8668553 = 8668642
- 239 + 8668403 = 8668642
- 263 + 8668379 = 8668642
- 293 + 8668349 = 8668642
- 449 + 8668193 = 8668642
Showing the first eight; more decompositions exist.
