Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17722, here are decompositions:
- 41 + 17681 = 17722
- 53 + 17669 = 17722
- 113 + 17609 = 17722
- 149 + 17573 = 17722
- 233 + 17489 = 17722
- 239 + 17483 = 17722
- 251 + 17471 = 17722
- 389 + 17333 = 17722
Showing the first eight; more decompositions exist.
