Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481078, here are decompositions:

  • 7 + 2147481071 = 2147481078
  • 47 + 2147481031 = 2147481078
  • 59 + 2147481019 = 2147481078
  • 89 + 2147480989 = 2147481078
  • 107 + 2147480971 = 2147481078
  • 109 + 2147480969 = 2147481078
  • 137 + 2147480941 = 2147481078
  • 151 + 2147480927 = 2147481078

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.245.246.

Address
127.255.245.246
Class
