Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477188, here are decompositions:

29 + 2147477159 = 2147477188
167 + 2147477021 = 2147477188
251 + 2147476937 = 2147477188
257 + 2147476931 = 2147477188
317 + 2147476871 = 2147477188
347 + 2147476841 = 2147477188
419 + 2147476769 = 2147477188
449 + 2147476739 = 2147477188

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.230.196.

Address: 127.255.230.196
