Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490042, here are decompositions:

31 + 2147490011 = 2147490042
73 + 2147489969 = 2147490042
101 + 2147489941 = 2147490042
193 + 2147489849 = 2147490042
199 + 2147489843 = 2147490042
223 + 2147489819 = 2147490042
389 + 2147489653 = 2147490042
463 + 2147489579 = 2147490042

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.24.250.

Address: 128.0.24.250
