Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488546, here are decompositions:

3 + 2147488543 = 2147488546
29 + 2147488517 = 2147488546
239 + 2147488307 = 2147488546
383 + 2147488163 = 2147488546
479 + 2147488067 = 2147488546
503 + 2147488043 = 2147488546
647 + 2147487899 = 2147488546
677 + 2147487869 = 2147488546

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.19.34.
