Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443888, here are decompositions:

89 + 2147443799 = 2147443888
101 + 2147443787 = 2147443888
167 + 2147443721 = 2147443888
467 + 2147443421 = 2147443888
677 + 2147443211 = 2147443888
719 + 2147443169 = 2147443888
839 + 2147443049 = 2147443888
911 + 2147442977 = 2147443888

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.100.176.

Address: 127.255.100.176
