Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500538, here are decompositions:

31 + 2147500507 = 2147500538
199 + 2147500339 = 2147500538
241 + 2147500297 = 2147500538
457 + 2147500081 = 2147500538
541 + 2147499997 = 2147500538
577 + 2147499961 = 2147500538
709 + 2147499829 = 2147500538
811 + 2147499727 = 2147500538

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.65.250.

Address: 128.0.65.250
Class: public
IPv4-mapped IPv6: ::ffff:128.0.65.250
