Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16646, here are decompositions:
- 13 + 16633 = 16646
- 43 + 16603 = 16646
- 73 + 16573 = 16646
- 79 + 16567 = 16646
- 127 + 16519 = 16646
- 193 + 16453 = 16646
- 199 + 16447 = 16646
- 229 + 16417 = 16646
Showing the first eight; more decompositions exist.
