Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484044, here are decompositions:

3 + 2147484041 = 2147484044
7 + 2147484037 = 2147484044
37 + 2147484007 = 2147484044
151 + 2147483893 = 2147484044
157 + 2147483887 = 2147484044
331 + 2147483713 = 2147484044
397 + 2147483647 = 2147484044
457 + 2147483587 = 2147484044

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.1.140.
