Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481846, here are decompositions:

19 + 2147481827 = 2147481846
53 + 2147481793 = 2147481846
173 + 2147481673 = 2147481846
283 + 2147481563 = 2147481846
317 + 2147481529 = 2147481846
337 + 2147481509 = 2147481846
347 + 2147481499 = 2147481846
359 + 2147481487 = 2147481846

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.248.246.

Address: 127.255.248.246
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.248.246
