Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544686, here are decompositions:
- 29 + 31544657 = 31544686
- 113 + 31544573 = 31544686
- 269 + 31544417 = 31544686
- 293 + 31544393 = 31544686
- 389 + 31544297 = 31544686
- 479 + 31544207 = 31544686
- 587 + 31544099 = 31544686
- 647 + 31544039 = 31544686
Showing the first eight; more decompositions exist.
