Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584636, here are decompositions:

83 + 2147584553 = 2147584636
107 + 2147584529 = 2147584636
179 + 2147584457 = 2147584636
293 + 2147584343 = 2147584636
359 + 2147584277 = 2147584636
383 + 2147584253 = 2147584636
479 + 2147584157 = 2147584636
647 + 2147583989 = 2147584636

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.138.124.
