Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491358, here are decompositions:

97 + 2147491261 = 2147491358
109 + 2147491249 = 2147491358
139 + 2147491219 = 2147491358
157 + 2147491201 = 2147491358
277 + 2147491081 = 2147491358
487 + 2147490871 = 2147491358
547 + 2147490811 = 2147491358
619 + 2147490739 = 2147491358

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.30.30.

Address: 128.0.30.30
Class: public
IPv4-mapped IPv6: ::ffff:128.0.30.30
