Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499998, here are decompositions:

37 + 2147499961 = 2147499998
157 + 2147499841 = 2147499998
271 + 2147499727 = 2147499998
421 + 2147499577 = 2147499998
487 + 2147499511 = 2147499998
541 + 2147499457 = 2147499998
547 + 2147499451 = 2147499998
607 + 2147499391 = 2147499998

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.63.222.

Address: 128.0.63.222
