Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147585976, here are decompositions:

5 + 2147585971 = 2147585976
13 + 2147585963 = 2147585976
17 + 2147585959 = 2147585976
23 + 2147585953 = 2147585976
37 + 2147585939 = 2147585976
79 + 2147585897 = 2147585976
83 + 2147585893 = 2147585976
139 + 2147585837 = 2147585976

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.143.184.

Address: 128.1.143.184
