Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425676, here are decompositions:
- 13 + 2147425663 = 2147425676
- 157 + 2147425519 = 2147425676
- 163 + 2147425513 = 2147425676
- 223 + 2147425453 = 2147425676
- 229 + 2147425447 = 2147425676
- 283 + 2147425393 = 2147425676
- 367 + 2147425309 = 2147425676
- 379 + 2147425297 = 2147425676
Showing the first eight; more decompositions exist.
