Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492020, here are decompositions:

59 + 2147491961 = 2147492020
83 + 2147491937 = 2147492020
239 + 2147491781 = 2147492020
263 + 2147491757 = 2147492020
461 + 2147491559 = 2147492020
467 + 2147491553 = 2147492020
503 + 2147491517 = 2147492020
617 + 2147491403 = 2147492020

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.32.180.

Address: 128.0.32.180
Class: public
IPv4-mapped IPv6: ::ffff:128.0.32.180
