Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425700, here are decompositions:
- 19 + 2147425681 = 2147425700
- 37 + 2147425663 = 2147425700
- 109 + 2147425591 = 2147425700
- 181 + 2147425519 = 2147425700
- 193 + 2147425507 = 2147425700
- 307 + 2147425393 = 2147425700
- 367 + 2147425333 = 2147425700
- 457 + 2147425243 = 2147425700
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 127.255.29.164.
