Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16422, here are decompositions:
- 5 + 16417 = 16422
- 11 + 16411 = 16422
- 41 + 16381 = 16422
- 53 + 16369 = 16422
- 59 + 16363 = 16422
- 61 + 16361 = 16422
- 73 + 16349 = 16422
- 83 + 16339 = 16422
Showing the first eight; more decompositions exist.
