Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426722, here are decompositions:
- 29 + 2147426693 = 2147426722
- 41 + 2147426681 = 2147426722
- 53 + 2147426669 = 2147426722
- 71 + 2147426651 = 2147426722
- 149 + 2147426573 = 2147426722
- 179 + 2147426543 = 2147426722
- 251 + 2147426471 = 2147426722
- 263 + 2147426459 = 2147426722
Showing the first eight; more decompositions exist.
