Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387852, here are decompositions:
- 13 + 2147387839 = 2147387852
- 31 + 2147387821 = 2147387852
- 61 + 2147387791 = 2147387852
- 109 + 2147387743 = 2147387852
- 139 + 2147387713 = 2147387852
- 223 + 2147387629 = 2147387852
- 349 + 2147387503 = 2147387852
- 439 + 2147387413 = 2147387852
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 127.254.137.204.
