Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12678, here are decompositions:
- 7 + 12671 = 12678
- 19 + 12659 = 12678
- 31 + 12647 = 12678
- 37 + 12641 = 12678
- 41 + 12637 = 12678
- 59 + 12619 = 12678
- 67 + 12611 = 12678
- 89 + 12589 = 12678
Showing the first eight; more decompositions exist.
