Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485274, here are decompositions:

7 + 2147485267 = 2147485274
13 + 2147485261 = 2147485274
73 + 2147485201 = 2147485274
283 + 2147484991 = 2147485274
313 + 2147484961 = 2147485274
397 + 2147484877 = 2147485274
523 + 2147484751 = 2147485274
541 + 2147484733 = 2147485274

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.6.90.

Address: 128.0.6.90
Class: public
IPv4-mapped IPv6: ::ffff:128.0.6.90

Public, routable address (assignable to a host on the internet).
