Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484572, here are decompositions:

3 + 2147484569 = 2147484572
19 + 2147484553 = 2147484572
31 + 2147484541 = 2147484572
73 + 2147484499 = 2147484572
139 + 2147484433 = 2147484572
223 + 2147484349 = 2147484572
241 + 2147484331 = 2147484572
313 + 2147484259 = 2147484572

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.3.156.

Address: 128.0.3.156
Class: public
IPv4-mapped IPv6: ::ffff:128.0.3.156
