Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12424, here are decompositions:
- 3 + 12421 = 12424
- 11 + 12413 = 12424
- 23 + 12401 = 12424
- 47 + 12377 = 12424
- 101 + 12323 = 12424
- 173 + 12251 = 12424
- 197 + 12227 = 12424
- 227 + 12197 = 12424
Showing the first eight; more decompositions exist.
