Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68828, here are decompositions:
- 7 + 68821 = 68828
- 37 + 68791 = 68828
- 61 + 68767 = 68828
- 79 + 68749 = 68828
- 307 + 68521 = 68828
- 337 + 68491 = 68828
- 379 + 68449 = 68828
- 439 + 68389 = 68828
Showing the first eight; more decompositions exist.
