Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20396, here are decompositions:
- 3 + 20393 = 20396
- 7 + 20389 = 20396
- 37 + 20359 = 20396
- 43 + 20353 = 20396
- 73 + 20323 = 20396
- 109 + 20287 = 20396
- 127 + 20269 = 20396
- 163 + 20233 = 20396
Showing the first eight; more decompositions exist.
