Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489688, here are decompositions:

37 + 2147489651 = 2147489688
101 + 2147489587 = 2147489688
109 + 2147489579 = 2147489688
151 + 2147489537 = 2147489688
251 + 2147489437 = 2147489688
389 + 2147489299 = 2147489688
397 + 2147489291 = 2147489688
599 + 2147489089 = 2147489688

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.23.152.

Address: 128.0.23.152
Class: public
IPv4-mapped IPv6: ::ffff:128.0.23.152
