Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20732, here are decompositions:
- 13 + 20719 = 20732
- 139 + 20593 = 20732
- 181 + 20551 = 20732
- 199 + 20533 = 20732
- 211 + 20521 = 20732
- 223 + 20509 = 20732
- 373 + 20359 = 20732
- 379 + 20353 = 20732
Showing the first eight; more decompositions exist.
