Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19422, here are decompositions:
- 5 + 19417 = 19422
- 19 + 19403 = 19422
- 31 + 19391 = 19422
- 41 + 19381 = 19422
- 43 + 19379 = 19422
- 89 + 19333 = 19422
- 103 + 19319 = 19422
- 113 + 19309 = 19422
Showing the first eight; more decompositions exist.
