Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12258, here are decompositions:
- 5 + 12253 = 12258
- 7 + 12251 = 12258
- 17 + 12241 = 12258
- 19 + 12239 = 12258
- 31 + 12227 = 12258
- 47 + 12211 = 12258
- 61 + 12197 = 12258
- 97 + 12161 = 12258
Showing the first eight; more decompositions exist.
