Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13286, here are decompositions:
- 19 + 13267 = 13286
- 37 + 13249 = 13286
- 67 + 13219 = 13286
- 103 + 13183 = 13286
- 109 + 13177 = 13286
- 127 + 13159 = 13286
- 139 + 13147 = 13286
- 193 + 13093 = 13286
Showing the first eight; more decompositions exist.
