Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489670, here are decompositions:

17 + 2147489653 = 2147489670
19 + 2147489651 = 2147489670
31 + 2147489639 = 2147489670
83 + 2147489587 = 2147489670
127 + 2147489543 = 2147489670
167 + 2147489503 = 2147489670
197 + 2147489473 = 2147489670
229 + 2147489441 = 2147489670

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.23.134.

Address: 128.0.23.134
