Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489378, here are decompositions:

31 + 2147489347 = 2147489378
79 + 2147489299 = 2147489378
967 + 2147488411 = 2147489378
997 + 2147488381 = 2147489378
1129 + 2147488249 = 2147489378
1447 + 2147487931 = 2147489378
1471 + 2147487907 = 2147489378
1549 + 2147487829 = 2147489378

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.22.98.
