Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 50686, here are decompositions:
- 3 + 50683 = 50686
- 59 + 50627 = 50686
- 137 + 50549 = 50686
- 173 + 50513 = 50686
- 227 + 50459 = 50686
- 263 + 50423 = 50686
- 269 + 50417 = 50686
- 353 + 50333 = 50686
Showing the first eight; more decompositions exist.
