Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426794, here are decompositions:
- 47 + 2147426747 = 2147426794
- 101 + 2147426693 = 2147426794
- 113 + 2147426681 = 2147426794
- 137 + 2147426657 = 2147426794
- 251 + 2147426543 = 2147426794
- 587 + 2147426207 = 2147426794
- 641 + 2147426153 = 2147426794
- 647 + 2147426147 = 2147426794
Showing the first eight; more decompositions exist.
