Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17212, here are decompositions:
- 3 + 17209 = 17212
- 5 + 17207 = 17212
- 23 + 17189 = 17212
- 29 + 17183 = 17212
- 53 + 17159 = 17212
- 89 + 17123 = 17212
- 113 + 17099 = 17212
- 179 + 17033 = 17212
Showing the first eight; more decompositions exist.
