Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491288, here are decompositions:
- 11 + 2147491277 = 2147491288
- 71 + 2147491217 = 2147491288
- 149 + 2147491139 = 2147491288
- 197 + 2147491091 = 2147491288
- 227 + 2147491061 = 2147491288
- 251 + 2147491037 = 2147491288
- 269 + 2147491019 = 2147491288
- 281 + 2147491007 = 2147491288
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 128.0.29.216.
