Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147587078, here are decompositions:

17 + 2147587061 = 2147587078
107 + 2147586971 = 2147587078
137 + 2147586941 = 2147587078
167 + 2147586911 = 2147587078
347 + 2147586731 = 2147587078
467 + 2147586611 = 2147587078
479 + 2147586599 = 2147587078
569 + 2147586509 = 2147587078

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.148.6.
