Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125668, here are decompositions:
- 17 + 125651 = 125668
- 29 + 125639 = 125668
- 41 + 125627 = 125668
- 47 + 125621 = 125668
- 71 + 125597 = 125668
- 197 + 125471 = 125668
- 227 + 125441 = 125668
- 239 + 125429 = 125668
Showing the first eight; more decompositions exist.
