Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2422, here are decompositions:
- 5 + 2417 = 2422
- 11 + 2411 = 2422
- 23 + 2399 = 2422
- 29 + 2393 = 2422
- 41 + 2381 = 2422
- 71 + 2351 = 2422
- 83 + 2339 = 2422
- 89 + 2333 = 2422
Showing the first eight; more decompositions exist.
