Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490830, here are decompositions:

19 + 2147490811 = 2147490830
31 + 2147490799 = 2147490830
61 + 2147490769 = 2147490830
103 + 2147490727 = 2147490830
241 + 2147490589 = 2147490830
367 + 2147490463 = 2147490830
379 + 2147490451 = 2147490830
487 + 2147490343 = 2147490830

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.28.14.
