Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485756, here are decompositions:

83 + 2147485673 = 2147485756
107 + 2147485649 = 2147485756
197 + 2147485559 = 2147485756
233 + 2147485523 = 2147485756
239 + 2147485517 = 2147485756
257 + 2147485499 = 2147485756
419 + 2147485337 = 2147485756
503 + 2147485253 = 2147485756

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.8.60.
