Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78866, here are decompositions:
- 13 + 78853 = 78866
- 43 + 78823 = 78866
- 79 + 78787 = 78866
- 223 + 78643 = 78866
- 283 + 78583 = 78866
- 313 + 78553 = 78866
- 349 + 78517 = 78866
- 379 + 78487 = 78866
Showing the first eight; more decompositions exist.
