Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491088, here are decompositions:

7 + 2147491081 = 2147491088
19 + 2147491069 = 2147491088
277 + 2147490811 = 2147491088
349 + 2147490739 = 2147491088
499 + 2147490589 = 2147491088
601 + 2147490487 = 2147491088
727 + 2147490361 = 2147491088
859 + 2147490229 = 2147491088

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.29.16.
