Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426888, here are decompositions:
- 67 + 2147426821 = 2147426888
- 331 + 2147426557 = 2147426888
- 337 + 2147426551 = 2147426888
- 367 + 2147426521 = 2147426888
- 421 + 2147426467 = 2147426888
- 487 + 2147426401 = 2147426888
- 571 + 2147426317 = 2147426888
- 727 + 2147426161 = 2147426888
Showing the first eight; more decompositions exist.
