Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500388, here are decompositions:

37 + 2147500351 = 2147500388
211 + 2147500177 = 2147500388
277 + 2147500111 = 2147500388
307 + 2147500081 = 2147500388
547 + 2147499841 = 2147500388
661 + 2147499727 = 2147500388
811 + 2147499577 = 2147500388
877 + 2147499511 = 2147500388

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.65.100.

Address: 128.0.65.100
Class: public
IPv4-mapped IPv6: ::ffff:128.0.65.100
