Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17218, here are decompositions:
- 11 + 17207 = 17218
- 29 + 17189 = 17218
- 59 + 17159 = 17218
- 101 + 17117 = 17218
- 191 + 17027 = 17218
- 197 + 17021 = 17218
- 239 + 16979 = 17218
- 281 + 16937 = 17218
Showing the first eight; more decompositions exist.
