Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128068, here are decompositions:
- 47 + 128021 = 128068
- 71 + 127997 = 128068
- 89 + 127979 = 128068
- 137 + 127931 = 128068
- 191 + 127877 = 128068
- 251 + 127817 = 128068
- 359 + 127709 = 128068
- 389 + 127679 = 128068
Showing the first eight; more decompositions exist.
