Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12646, here are decompositions:
- 5 + 12641 = 12646
- 107 + 12539 = 12646
- 149 + 12497 = 12646
- 167 + 12479 = 12646
- 173 + 12473 = 12646
- 233 + 12413 = 12646
- 269 + 12377 = 12646
- 317 + 12329 = 12646
Showing the first eight; more decompositions exist.
