Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12398, here are decompositions:
- 7 + 12391 = 12398
- 19 + 12379 = 12398
- 97 + 12301 = 12398
- 109 + 12289 = 12398
- 157 + 12241 = 12398
- 241 + 12157 = 12398
- 349 + 12049 = 12398
- 439 + 11959 = 12398
Showing the first eight; more decompositions exist.
