Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501990, here are decompositions:

3 + 2147501987 = 2147501990
19 + 2147501971 = 2147501990
31 + 2147501959 = 2147501990
103 + 2147501887 = 2147501990
241 + 2147501749 = 2147501990
307 + 2147501683 = 2147501990
313 + 2147501677 = 2147501990
367 + 2147501623 = 2147501990

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.71.166.

Address: 128.0.71.166
Class: public
