Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493548, here are decompositions:

139 + 2147493409 = 2147493548
157 + 2147493391 = 2147493548
271 + 2147493277 = 2147493548
307 + 2147493241 = 2147493548
379 + 2147493169 = 2147493548
439 + 2147493109 = 2147493548
547 + 2147493001 = 2147493548
619 + 2147492929 = 2147493548

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.38.172.

Address: 128.0.38.172
