Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584838, here are decompositions:

31 + 2147584807 = 2147584838
181 + 2147584657 = 2147584838
229 + 2147584609 = 2147584838
241 + 2147584597 = 2147584838
337 + 2147584501 = 2147584838
769 + 2147584069 = 2147584838
877 + 2147583961 = 2147584838
1009 + 2147583829 = 2147584838

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.139.70.
