Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17220, here are decompositions:
- 11 + 17209 = 17220
- 13 + 17207 = 17220
- 17 + 17203 = 17220
- 29 + 17191 = 17220
- 31 + 17189 = 17220
- 37 + 17183 = 17220
- 53 + 17167 = 17220
- 61 + 17159 = 17220
Showing the first eight; more decompositions exist.
