Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501242, here are decompositions:

113 + 2147501129 = 2147501242
233 + 2147501009 = 2147501242
311 + 2147500931 = 2147501242
353 + 2147500889 = 2147501242
461 + 2147500781 = 2147501242
479 + 2147500763 = 2147501242
683 + 2147500559 = 2147501242
743 + 2147500499 = 2147501242

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.68.186.

Address: 128.0.68.186
Class: public
IPv4-mapped IPv6: ::ffff:128.0.68.186
