Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481748, here are decompositions:

239 + 2147481509 = 2147481748
257 + 2147481491 = 2147481748
389 + 2147481359 = 2147481748
431 + 2147481317 = 2147481748
479 + 2147481269 = 2147481748
569 + 2147481179 = 2147481748
677 + 2147481071 = 2147481748
821 + 2147480927 = 2147481748

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.248.148.

Address: 127.255.248.148
