Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12418, here are decompositions:
- 5 + 12413 = 12418
- 17 + 12401 = 12418
- 41 + 12377 = 12418
- 71 + 12347 = 12418
- 89 + 12329 = 12418
- 137 + 12281 = 12418
- 149 + 12269 = 12418
- 167 + 12251 = 12418
Showing the first eight; more decompositions exist.
