Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500142, here are decompositions:

3 + 2147500139 = 2147500142
19 + 2147500123 = 2147500142
31 + 2147500111 = 2147500142
61 + 2147500081 = 2147500142
79 + 2147500063 = 2147500142
181 + 2147499961 = 2147500142
313 + 2147499829 = 2147500142
439 + 2147499703 = 2147500142

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.64.110.

Address: 128.0.64.110
Class: public
IPv4-mapped IPv6: ::ffff:128.0.64.110
