Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488100, here are decompositions:

73 + 2147488027 = 2147488100
193 + 2147487907 = 2147488100
229 + 2147487871 = 2147488100
271 + 2147487829 = 2147488100
283 + 2147487817 = 2147488100
349 + 2147487751 = 2147488100
397 + 2147487703 = 2147488100
409 + 2147487691 = 2147488100

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.17.100.

Address: 128.0.17.100
