Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490890, here are decompositions:
- 7 + 2147490883 = 2147490890
- 19 + 2147490871 = 2147490890
- 79 + 2147490811 = 2147490890
- 151 + 2147490739 = 2147490890
- 163 + 2147490727 = 2147490890
- 313 + 2147490577 = 2147490890
- 439 + 2147490451 = 2147490890
- 547 + 2147490343 = 2147490890
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 128.0.28.74.
