Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493248, here are decompositions:

7 + 2147493241 = 2147493248
79 + 2147493169 = 2147493248
139 + 2147493109 = 2147493248
211 + 2147493037 = 2147493248
547 + 2147492701 = 2147493248
577 + 2147492671 = 2147493248
709 + 2147492539 = 2147493248
727 + 2147492521 = 2147493248

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.37.128.

Address: 128.0.37.128
