Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488932, here are decompositions:

13 + 2147488919 = 2147488932
19 + 2147488913 = 2147488932
73 + 2147488859 = 2147488932
139 + 2147488793 = 2147488932
181 + 2147488751 = 2147488932
191 + 2147488741 = 2147488932
241 + 2147488691 = 2147488932
313 + 2147488619 = 2147488932

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.20.164.
