Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16290, here are decompositions:
- 17 + 16273 = 16290
- 23 + 16267 = 16290
- 37 + 16253 = 16290
- 41 + 16249 = 16290
- 59 + 16231 = 16290
- 61 + 16229 = 16290
- 67 + 16223 = 16290
- 73 + 16217 = 16290
Showing the first eight; more decompositions exist.
