Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478162, here are decompositions:

  • 13 + 2147478149 = 2147478162
  • 29 + 2147478133 = 2147478162
  • 73 + 2147478089 = 2147478162
  • 79 + 2147478083 = 2147478162
  • 83 + 2147478079 = 2147478162
  • 113 + 2147478049 = 2147478162
  • 149 + 2147478013 = 2147478162
  • 173 + 2147477989 = 2147478162

Showing the first eight; more decompositions exist.

IPv4 address
