Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147474892, here are decompositions:

  • 5 + 2147474887 = 2147474892
  • 11 + 2147474881 = 2147474892
  • 41 + 2147474851 = 2147474892
  • 61 + 2147474831 = 2147474892
  • 83 + 2147474809 = 2147474892
  • 89 + 2147474803 = 2147474892
  • 103 + 2147474789 = 2147474892
  • 181 + 2147474711 = 2147474892

Showing the first eight; more decompositions exist.

IPv4 address
