Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39686, here are decompositions:
- 7 + 39679 = 39686
- 19 + 39667 = 39686
- 67 + 39619 = 39686
- 79 + 39607 = 39686
- 277 + 39409 = 39686
- 313 + 39373 = 39686
- 373 + 39313 = 39686
- 457 + 39229 = 39686
Showing the first eight; more decompositions exist.
