Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422726, here are decompositions:
- 3 + 2147422723 = 2147422726
- 23 + 2147422703 = 2147422726
- 47 + 2147422679 = 2147422726
- 167 + 2147422559 = 2147422726
- 233 + 2147422493 = 2147422726
- 263 + 2147422463 = 2147422726
- 269 + 2147422457 = 2147422726
- 353 + 2147422373 = 2147422726
Showing the first eight; more decompositions exist.
