Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501138, here are decompositions:

7 + 2147501131 = 2147501138
37 + 2147501101 = 2147501138
61 + 2147501077 = 2147501138
151 + 2147500987 = 2147501138
157 + 2147500981 = 2147501138
229 + 2147500909 = 2147501138
547 + 2147500591 = 2147501138
577 + 2147500561 = 2147501138

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.68.82.
