Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294966440, here are decompositions:
- 13 + 4294966427 = 4294966440
- 67 + 4294966373 = 4294966440
- 73 + 4294966367 = 4294966440
- 103 + 4294966337 = 4294966440
- 197 + 4294966243 = 4294966440
- 223 + 4294966217 = 4294966440
- 263 + 4294966177 = 4294966440
- 277 + 4294966163 = 4294966440
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 255.255.252.168.
