Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12444, here are decompositions:
- 7 + 12437 = 12444
- 11 + 12433 = 12444
- 23 + 12421 = 12444
- 31 + 12413 = 12444
- 43 + 12401 = 12444
- 53 + 12391 = 12444
- 67 + 12377 = 12444
- 71 + 12373 = 12444
Showing the first eight; more decompositions exist.
