Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490292, here are decompositions:

29 + 2147490263 = 2147490292
53 + 2147490239 = 2147490292
131 + 2147490161 = 2147490292
239 + 2147490053 = 2147490292
281 + 2147490011 = 2147490292
383 + 2147489909 = 2147490292
419 + 2147489873 = 2147490292
443 + 2147489849 = 2147490292

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.25.244.

Address: 128.0.25.244
Class: public
IPv4-mapped IPv6: ::ffff:128.0.25.244
