Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489196, here are decompositions:

53 + 2147489143 = 2147489196
107 + 2147489089 = 2147489196
109 + 2147489087 = 2147489196
113 + 2147489083 = 2147489196
137 + 2147489059 = 2147489196
173 + 2147489023 = 2147489196
179 + 2147489017 = 2147489196
199 + 2147488997 = 2147489196

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.21.172.

Address: 128.0.21.172
