Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147480770, here are decompositions:

  • 23 + 2147480747 = 2147480770
  • 47 + 2147480723 = 2147480770
  • 179 + 2147480591 = 2147480770
  • 251 + 2147480519 = 2147480770
  • 263 + 2147480507 = 2147480770
  • 311 + 2147480459 = 2147480770
  • 401 + 2147480369 = 2147480770
  • 443 + 2147480327 = 2147480770

Showing the first eight; more decompositions exist.

IPv4 address
