Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491740, here are decompositions:

7 + 2147491733 = 2147491740
41 + 2147491699 = 2147491740
131 + 2147491609 = 2147491740
137 + 2147491603 = 2147491740
157 + 2147491583 = 2147491740
167 + 2147491573 = 2147491740
181 + 2147491559 = 2147491740
193 + 2147491547 = 2147491740

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.31.156.

Address: 128.0.31.156
