Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125808, here are decompositions:
- 5 + 125803 = 125808
- 17 + 125791 = 125808
- 19 + 125789 = 125808
- 31 + 125777 = 125808
- 71 + 125737 = 125808
- 97 + 125711 = 125808
- 101 + 125707 = 125808
- 139 + 125669 = 125808
Showing the first eight; more decompositions exist.
