Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425712, here are decompositions:
- 31 + 2147425681 = 2147425712
- 181 + 2147425531 = 2147425712
- 193 + 2147425519 = 2147425712
- 199 + 2147425513 = 2147425712
- 331 + 2147425381 = 2147425712
- 379 + 2147425333 = 2147425712
- 463 + 2147425249 = 2147425712
- 499 + 2147425213 = 2147425712
Showing the first eight; more decompositions exist.
