Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493020, here are decompositions:

3 + 2147493017 = 2147493020
19 + 2147493001 = 2147493020
61 + 2147492959 = 2147493020
97 + 2147492923 = 2147493020
349 + 2147492671 = 2147493020
367 + 2147492653 = 2147493020
487 + 2147492533 = 2147493020
499 + 2147492521 = 2147493020

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.36.156.

Address: 128.0.36.156
Class: public
IPv4-mapped IPv6: ::ffff:128.0.36.156
