Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485722, here are decompositions:

73 + 2147485649 = 2147485722
131 + 2147485591 = 2147485722
149 + 2147485573 = 2147485722
163 + 2147485559 = 2147485722
199 + 2147485523 = 2147485722
223 + 2147485499 = 2147485722
271 + 2147485451 = 2147485722
311 + 2147485411 = 2147485722

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.8.26.
