Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2606, here are decompositions:
- 13 + 2593 = 2606
- 67 + 2539 = 2606
- 103 + 2503 = 2606
- 139 + 2467 = 2606
- 223 + 2383 = 2606
- 229 + 2377 = 2606
- 313 + 2293 = 2606
- 337 + 2269 = 2606
Showing the first eight; more decompositions exist.
