Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404926, here are decompositions:

67 + 2147404859 = 2147404926
97 + 2147404829 = 2147404926
307 + 2147404619 = 2147404926
347 + 2147404579 = 2147404926
349 + 2147404577 = 2147404926
479 + 2147404447 = 2147404926
487 + 2147404439 = 2147404926
577 + 2147404349 = 2147404926

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.254.204.126.

Address: 127.254.204.126
