Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404916, here are decompositions:

277 + 2147404639 = 2147404916
337 + 2147404579 = 2147404916
487 + 2147404429 = 2147404916
523 + 2147404393 = 2147404916
607 + 2147404309 = 2147404916
673 + 2147404243 = 2147404916
733 + 2147404183 = 2147404916
1447 + 2147403469 = 2147404916

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.254.204.116.

Address: 127.254.204.116
