Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488684, here are decompositions:

41 + 2147488643 = 2147488684
71 + 2147488613 = 2147488684
167 + 2147488517 = 2147488684
521 + 2147488163 = 2147488684
617 + 2147488067 = 2147488684
641 + 2147488043 = 2147488684
683 + 2147488001 = 2147488684
743 + 2147487941 = 2147488684

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.19.172.

Address: 128.0.19.172
