Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488848, here are decompositions:

  • 97 + 2147488751 = 2147488848
  • 107 + 2147488741 = 2147488848
  • 157 + 2147488691 = 2147488848
  • 229 + 2147488619 = 2147488848
  • 269 + 2147488579 = 2147488848
  • 331 + 2147488517 = 2147488848
  • 419 + 2147488429 = 2147488848
  • 431 + 2147488417 = 2147488848

Showing the first eight; more decompositions exist.

IPv4 address
