Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492774, here are decompositions:

73 + 2147492701 = 2147492774
103 + 2147492671 = 2147492774
223 + 2147492551 = 2147492774
241 + 2147492533 = 2147492774
283 + 2147492491 = 2147492774
421 + 2147492353 = 2147492774
457 + 2147492317 = 2147492774
613 + 2147492161 = 2147492774

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.35.166.

Address: 128.0.35.166
Class: public
IPv4-mapped IPv6: ::ffff:128.0.35.166
