Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425964, here are decompositions:
- 31 + 2147425933 = 2147425964
- 283 + 2147425681 = 2147425964
- 373 + 2147425591 = 2147425964
- 433 + 2147425531 = 2147425964
- 457 + 2147425507 = 2147425964
- 571 + 2147425393 = 2147425964
- 631 + 2147425333 = 2147425964
- 727 + 2147425237 = 2147425964
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 127.255.30.172.
