Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16266, here are decompositions:
- 13 + 16253 = 16266
- 17 + 16249 = 16266
- 37 + 16229 = 16266
- 43 + 16223 = 16266
- 73 + 16193 = 16266
- 79 + 16187 = 16266
- 83 + 16183 = 16266
- 127 + 16139 = 16266
Showing the first eight; more decompositions exist.
