Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967238, here are decompositions:
- 7 + 4294967231 = 4294967238
- 41 + 4294967197 = 4294967238
- 127 + 4294967111 = 4294967238
- 151 + 4294967087 = 4294967238
- 241 + 4294966997 = 4294967238
- 257 + 4294966981 = 4294967238
- 311 + 4294966927 = 4294967238
- 409 + 4294966829 = 4294967238
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 255.255.255.198.
