Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12286, here are decompositions:
- 5 + 12281 = 12286
- 17 + 12269 = 12286
- 23 + 12263 = 12286
- 47 + 12239 = 12286
- 59 + 12227 = 12286
- 83 + 12203 = 12286
- 89 + 12197 = 12286
- 137 + 12149 = 12286
Showing the first eight; more decompositions exist.
