Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122422, here are decompositions:
- 23 + 122399 = 122422
- 29 + 122393 = 122422
- 59 + 122363 = 122422
- 101 + 122321 = 122422
- 149 + 122273 = 122422
- 191 + 122231 = 122422
- 353 + 122069 = 122422
- 383 + 122039 = 122422
Showing the first eight; more decompositions exist.
