Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20422, here are decompositions:
- 11 + 20411 = 20422
- 23 + 20399 = 20422
- 29 + 20393 = 20422
- 53 + 20369 = 20422
- 89 + 20333 = 20422
- 173 + 20249 = 20422
- 191 + 20231 = 20422
- 239 + 20183 = 20422
Showing the first eight; more decompositions exist.
