Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967128, here are decompositions:
- 17 + 4294967111 = 4294967128
- 41 + 4294967087 = 4294967128
- 131 + 4294966997 = 4294967128
- 251 + 4294966877 = 4294967128
- 359 + 4294966769 = 4294967128
- 461 + 4294966667 = 4294967128
- 467 + 4294966661 = 4294967128
- 509 + 4294966619 = 4294967128
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 255.255.255.88.
