Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967172, here are decompositions:
- 11 + 4294967161 = 4294967172
- 29 + 4294967143 = 4294967172
- 61 + 4294967111 = 4294967172
- 191 + 4294966981 = 4294967172
- 229 + 4294966943 = 4294967172
- 263 + 4294966909 = 4294967172
- 359 + 4294966813 = 4294967172
- 521 + 4294966651 = 4294967172
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 255.255.255.132.
