Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481672, here are decompositions:

  • 43 + 2147481629 = 2147481672
  • 101 + 2147481571 = 2147481672
  • 109 + 2147481563 = 2147481672
  • 163 + 2147481509 = 2147481672
  • 173 + 2147481499 = 2147481672
  • 181 + 2147481491 = 2147481672
  • 313 + 2147481359 = 2147481672
  • 389 + 2147481283 = 2147481672

Showing the first eight; more decompositions exist.

IPv4 address
