Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490546, here are decompositions:

7 + 2147490539 = 2147490546
17 + 2147490529 = 2147490546
59 + 2147490487 = 2147490546
83 + 2147490463 = 2147490546
263 + 2147490283 = 2147490546
283 + 2147490263 = 2147490546
307 + 2147490239 = 2147490546
317 + 2147490229 = 2147490546

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.26.242.

Address: 128.0.26.242
Class: public
IPv4-mapped IPv6: ::ffff:128.0.26.242
