Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499620, here are decompositions:

3 + 2147499617 = 2147499620
43 + 2147499577 = 2147499620
73 + 2147499547 = 2147499620
109 + 2147499511 = 2147499620
139 + 2147499481 = 2147499620
163 + 2147499457 = 2147499620
229 + 2147499391 = 2147499620
241 + 2147499379 = 2147499620

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.62.100.

Address: 128.0.62.100
Class: public
IPv4-mapped IPv6: ::ffff:128.0.62.100
