Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429108, here are decompositions:

37 + 2147429071 = 2147429108
61 + 2147429047 = 2147429108
109 + 2147428999 = 2147429108
127 + 2147428981 = 2147429108
151 + 2147428957 = 2147429108
271 + 2147428837 = 2147429108
421 + 2147428687 = 2147429108
547 + 2147428561 = 2147429108

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.42.244.

Address: 127.255.42.244
