Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481248, here are decompositions:

97 + 2147481151 = 2147481248
109 + 2147481139 = 2147481248
229 + 2147481019 = 2147481248
277 + 2147480971 = 2147481248
307 + 2147480941 = 2147481248
349 + 2147480899 = 2147481248
457 + 2147480791 = 2147481248
541 + 2147480707 = 2147481248

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.246.160.

Address: 127.255.246.160
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.246.160
