Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483778, here are decompositions:

131 + 2147483647 = 2147483778
149 + 2147483629 = 2147483778
191 + 2147483587 = 2147483778
199 + 2147483579 = 2147483778
229 + 2147483549 = 2147483778
281 + 2147483497 = 2147483778
379 + 2147483399 = 2147483778
509 + 2147483269 = 2147483778

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.0.130.

Address: 128.0.0.130
Class: public
IPv4-mapped IPv6: ::ffff:128.0.0.130
