Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485568, here are decompositions:

157 + 2147485411 = 2147485568
199 + 2147485369 = 2147485568
211 + 2147485357 = 2147485568
307 + 2147485261 = 2147485568
367 + 2147485201 = 2147485568
379 + 2147485189 = 2147485568
577 + 2147484991 = 2147485568
607 + 2147484961 = 2147485568

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.7.128.

Address: 128.0.7.128
