Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425982, here are decompositions:
- 3 + 2147425979 = 2147425982
- 103 + 2147425879 = 2147425982
- 223 + 2147425759 = 2147425982
- 271 + 2147425711 = 2147425982
- 463 + 2147425519 = 2147425982
- 571 + 2147425411 = 2147425982
- 601 + 2147425381 = 2147425982
- 673 + 2147425309 = 2147425982
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 127.255.30.190.
