Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481740, here are decompositions:

67 + 2147481673 = 2147481740
211 + 2147481529 = 2147481740
241 + 2147481499 = 2147481740
367 + 2147481373 = 2147481740
373 + 2147481367 = 2147481740
457 + 2147481283 = 2147481740
541 + 2147481199 = 2147481740
601 + 2147481139 = 2147481740

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.248.140.

Address: 127.255.248.140
