Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584972, here are decompositions:

23 + 2147584949 = 2147584972
101 + 2147584871 = 2147584972
191 + 2147584781 = 2147584972
293 + 2147584679 = 2147584972
311 + 2147584661 = 2147584972
419 + 2147584553 = 2147584972
443 + 2147584529 = 2147584972
719 + 2147584253 = 2147584972

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.139.204.

Address: 128.1.139.204
