Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12422, here are decompositions:
- 13 + 12409 = 12422
- 31 + 12391 = 12422
- 43 + 12379 = 12422
- 79 + 12343 = 12422
- 181 + 12241 = 12422
- 211 + 12211 = 12422
- 313 + 12109 = 12422
- 349 + 12073 = 12422
Showing the first eight; more decompositions exist.
