Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13186, here are decompositions:
- 3 + 13183 = 13186
- 23 + 13163 = 13186
- 59 + 13127 = 13186
- 83 + 13103 = 13186
- 137 + 13049 = 13186
- 149 + 13037 = 13186
- 179 + 13007 = 13186
- 227 + 12959 = 13186
Showing the first eight; more decompositions exist.
