Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483438, here are decompositions:

379 + 2147483059 = 2147483438
409 + 2147483029 = 2147483438
487 + 2147482951 = 2147483438
571 + 2147482867 = 2147483438
619 + 2147482819 = 2147483438
757 + 2147482681 = 2147483438
937 + 2147482501 = 2147483438
1021 + 2147482417 = 2147483438

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.255.46.

Address: 127.255.255.46
