Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499340, here are decompositions:

17 + 2147499323 = 2147499340
29 + 2147499311 = 2147499340
47 + 2147499293 = 2147499340
59 + 2147499281 = 2147499340
179 + 2147499161 = 2147499340
269 + 2147499071 = 2147499340
281 + 2147499059 = 2147499340
383 + 2147498957 = 2147499340

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.61.76.

Address: 128.0.61.76
Class: public
IPv4-mapped IPv6: ::ffff:128.0.61.76
