Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490524, here are decompositions:

37 + 2147490487 = 2147490524
61 + 2147490463 = 2147490524
73 + 2147490451 = 2147490524
163 + 2147490361 = 2147490524
181 + 2147490343 = 2147490524
241 + 2147490283 = 2147490524
307 + 2147490217 = 2147490524
463 + 2147490061 = 2147490524

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.26.220.

Address: 128.0.26.220
Class: public
IPv4-mapped IPv6: ::ffff:128.0.26.220
