Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426198, here are decompositions:
- 31 + 2147426167 = 2147426198
- 37 + 2147426161 = 2147426198
- 61 + 2147426137 = 2147426198
- 439 + 2147425759 = 2147426198
- 487 + 2147425711 = 2147426198
- 607 + 2147425591 = 2147426198
- 691 + 2147425507 = 2147426198
- 751 + 2147425447 = 2147426198
Showing the first eight; more decompositions exist.
