Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20522, here are decompositions:
- 13 + 20509 = 20522
- 43 + 20479 = 20522
- 79 + 20443 = 20522
- 163 + 20359 = 20522
- 181 + 20341 = 20522
- 199 + 20323 = 20522
- 349 + 20173 = 20522
- 373 + 20149 = 20522
Showing the first eight; more decompositions exist.
