Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489474, here are decompositions:

37 + 2147489437 = 2147489474
73 + 2147489401 = 2147489474
127 + 2147489347 = 2147489474
211 + 2147489263 = 2147489474
271 + 2147489203 = 2147489474
331 + 2147489143 = 2147489474
397 + 2147489077 = 2147489474
457 + 2147489017 = 2147489474

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.22.194.

Address: 128.0.22.194
