Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490860, here are decompositions:

61 + 2147490799 = 2147490860
271 + 2147490589 = 2147490860
283 + 2147490577 = 2147490860
331 + 2147490529 = 2147490860
373 + 2147490487 = 2147490860
397 + 2147490463 = 2147490860
409 + 2147490451 = 2147490860
499 + 2147490361 = 2147490860

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.28.44.

Address: 128.0.28.44
Class: public
IPv4-mapped IPv6: ::ffff:128.0.28.44
