Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12386, here are decompositions:
- 7 + 12379 = 12386
- 13 + 12373 = 12386
- 43 + 12343 = 12386
- 97 + 12289 = 12386
- 109 + 12277 = 12386
- 223 + 12163 = 12386
- 229 + 12157 = 12386
- 277 + 12109 = 12386
Showing the first eight; more decompositions exist.
