Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493678, here are decompositions:

7 + 2147493671 = 2147493678
17 + 2147493661 = 2147493678
61 + 2147493617 = 2147493678
79 + 2147493599 = 2147493678
89 + 2147493589 = 2147493678
131 + 2147493547 = 2147493678
199 + 2147493479 = 2147493678
269 + 2147493409 = 2147493678

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.39.46.

Address: 128.0.39.46
