Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485804, here are decompositions:

131 + 2147485673 = 2147485804
257 + 2147485547 = 2147485804
281 + 2147485523 = 2147485804
353 + 2147485451 = 2147485804
383 + 2147485421 = 2147485804
461 + 2147485343 = 2147485804
467 + 2147485337 = 2147485804
557 + 2147485247 = 2147485804

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.8.108.

Address: 128.0.8.108
