Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443994, here are decompositions:

433 + 2147443561 = 2147443994
457 + 2147443537 = 2147443994
523 + 2147443471 = 2147443994
571 + 2147443423 = 2147443994
691 + 2147443303 = 2147443994
823 + 2147443171 = 2147443994
907 + 2147443087 = 2147443994
937 + 2147443057 = 2147443994

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.101.26.

Address: 127.255.101.26
