Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42422, here are decompositions:
- 13 + 42409 = 42422
- 19 + 42403 = 42422
- 31 + 42391 = 42422
- 43 + 42379 = 42422
- 73 + 42349 = 42422
- 139 + 42283 = 42422
- 199 + 42223 = 42422
- 229 + 42193 = 42422
Showing the first eight; more decompositions exist.
