Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22558, here are decompositions:
- 17 + 22541 = 22558
- 47 + 22511 = 22558
- 89 + 22469 = 22558
- 149 + 22409 = 22558
- 167 + 22391 = 22558
- 191 + 22367 = 22558
- 251 + 22307 = 22558
- 281 + 22277 = 22558
Showing the first eight; more decompositions exist.
