Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484520, here are decompositions:

3 + 2147484517 = 2147484520
29 + 2147484491 = 2147484520
59 + 2147484461 = 2147484520
281 + 2147484239 = 2147484520
317 + 2147484203 = 2147484520
353 + 2147484167 = 2147484520
359 + 2147484161 = 2147484520
479 + 2147484041 = 2147484520

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.3.104.

Address: 128.0.3.104
Class: public
IPv4-mapped IPv6: ::ffff:128.0.3.104
