Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16616, here are decompositions:
- 13 + 16603 = 16616
- 43 + 16573 = 16616
- 97 + 16519 = 16616
- 139 + 16477 = 16616
- 163 + 16453 = 16616
- 199 + 16417 = 16616
- 277 + 16339 = 16616
- 283 + 16333 = 16616
Showing the first eight; more decompositions exist.
