Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490738, here are decompositions:

7 + 2147490731 = 2147490738
11 + 2147490727 = 2147490738
79 + 2147490659 = 2147490738
149 + 2147490589 = 2147490738
157 + 2147490581 = 2147490738
181 + 2147490557 = 2147490738
199 + 2147490539 = 2147490738
251 + 2147490487 = 2147490738

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.27.178.

Address: 128.0.27.178
