Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147549686, here are decompositions:

  • 3 + 2147549683 = 2147549686
  • 5 + 2147549681 = 2147549686
  • 83 + 2147549603 = 2147549686
  • 137 + 2147549549 = 2147549686
  • 179 + 2147549507 = 2147549686
  • 239 + 2147549447 = 2147549686
  • 389 + 2147549297 = 2147549686
  • 467 + 2147549219 = 2147549686

Showing the first eight; more decompositions exist.
