Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426408, here are decompositions:
- 7 + 2147426401 = 2147426408
- 31 + 2147426377 = 2147426408
- 79 + 2147426329 = 2147426408
- 241 + 2147426167 = 2147426408
- 271 + 2147426137 = 2147426408
- 727 + 2147425681 = 2147426408
- 877 + 2147425531 = 2147426408
- 997 + 2147425411 = 2147426408
Showing the first eight; more decompositions exist.
