Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498388, here are decompositions:

41 + 2147498347 = 2147498388
47 + 2147498341 = 2147498388
109 + 2147498279 = 2147498388
179 + 2147498209 = 2147498388
199 + 2147498189 = 2147498388
241 + 2147498147 = 2147498388
271 + 2147498117 = 2147498388
311 + 2147498077 = 2147498388

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.57.148.
