Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12456, here are decompositions:
- 5 + 12451 = 12456
- 19 + 12437 = 12456
- 23 + 12433 = 12456
- 43 + 12413 = 12456
- 47 + 12409 = 12456
- 79 + 12377 = 12456
- 83 + 12373 = 12456
- 109 + 12347 = 12456
Showing the first eight; more decompositions exist.
