Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429380, here are decompositions:

  • 17 + 2147429363 = 2147429380
  • 29 + 2147429351 = 2147429380
  • 71 + 2147429309 = 2147429380
  • 167 + 2147429213 = 2147429380
  • 197 + 2147429183 = 2147429380
  • 233 + 2147429147 = 2147429380
  • 389 + 2147428991 = 2147429380
  • 431 + 2147428949 = 2147429380

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.44.4.

Address
127.255.44.4
Class
