Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488246, here are decompositions:
- 83 + 2147488163 = 2147488246
- 179 + 2147488067 = 2147488246
- 347 + 2147487899 = 2147488246
- 419 + 2147487827 = 2147488246
- 443 + 2147487803 = 2147488246
- 467 + 2147487779 = 2147488246
- 557 + 2147487689 = 2147488246
- 647 + 2147487599 = 2147488246
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 128.0.17.246.
- Address
