Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127678, here are decompositions:
- 29 + 127649 = 127678
- 41 + 127637 = 127678
- 71 + 127607 = 127678
- 137 + 127541 = 127678
- 149 + 127529 = 127678
- 191 + 127487 = 127678
- 197 + 127481 = 127678
- 347 + 127331 = 127678
Showing the first eight; more decompositions exist.
