Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147587470, here are decompositions:

23 + 2147587447 = 2147587470
31 + 2147587439 = 2147587470
43 + 2147587427 = 2147587470
53 + 2147587417 = 2147587470
73 + 2147587397 = 2147587470
101 + 2147587369 = 2147587470
107 + 2147587363 = 2147587470
113 + 2147587357 = 2147587470

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.149.142.

Address: 128.1.149.142
