Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491572, here are decompositions:

13 + 2147491559 = 2147491572
19 + 2147491553 = 2147491572
29 + 2147491543 = 2147491572
211 + 2147491361 = 2147491572
223 + 2147491349 = 2147491572
229 + 2147491343 = 2147491572
311 + 2147491261 = 2147491572
349 + 2147491223 = 2147491572

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.30.244.

Address: 128.0.30.244
Class: public
IPv4-mapped IPv6: ::ffff:128.0.30.244
