Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492450, here are decompositions:

3 + 2147492447 = 2147492450
79 + 2147492371 = 2147492450
97 + 2147492353 = 2147492450
151 + 2147492299 = 2147492450
211 + 2147492239 = 2147492450
421 + 2147492029 = 2147492450
547 + 2147491903 = 2147492450
613 + 2147491837 = 2147492450

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.34.98.
