Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500728, here are decompositions:

5 + 2147500723 = 2147500728
31 + 2147500697 = 2147500728
67 + 2147500661 = 2147500728
101 + 2147500627 = 2147500728
137 + 2147500591 = 2147500728
167 + 2147500561 = 2147500728
229 + 2147500499 = 2147500728
367 + 2147500361 = 2147500728

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.66.184.

Address: 128.0.66.184
Class: public
IPv4-mapped IPv6: ::ffff:128.0.66.184
