Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523996, here are decompositions:

43 + 31523953 = 31523996
79 + 31523917 = 31523996
157 + 31523839 = 31523996
193 + 31523803 = 31523996
337 + 31523659 = 31523996
349 + 31523647 = 31523996
397 + 31523599 = 31523996
457 + 31523539 = 31523996

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.4.156.

Address: 1.225.4.156
Class: public
IPv4-mapped IPv6: ::ffff:1.225.4.156

Public, routable address (assignable to a host on the internet).
