Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487172, here are decompositions:

3 + 2147487169 = 2147487172
59 + 2147487113 = 2147487172
113 + 2147487059 = 2147487172
191 + 2147486981 = 2147487172
263 + 2147486909 = 2147487172
293 + 2147486879 = 2147487172
353 + 2147486819 = 2147487172
431 + 2147486741 = 2147487172

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.13.196.

Address: 128.0.13.196
