Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488688, here are decompositions:

109 + 2147488579 = 2147488688
271 + 2147488417 = 2147488688
277 + 2147488411 = 2147488688
307 + 2147488381 = 2147488688
409 + 2147488279 = 2147488688
439 + 2147488249 = 2147488688
577 + 2147488111 = 2147488688
661 + 2147488027 = 2147488688

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.19.176.

Address: 128.0.19.176
