Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497584, here are decompositions:

  • 13 + 2147497571 = 2147497584
  • 61 + 2147497523 = 2147497584
  • 103 + 2147497481 = 2147497584
  • 137 + 2147497447 = 2147497584
  • 173 + 2147497411 = 2147497584
  • 181 + 2147497403 = 2147497584
  • 191 + 2147497393 = 2147497584
  • 223 + 2147497361 = 2147497584

Showing the first eight; more decompositions exist.
