Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497734, here are decompositions:

  • 17 + 2147497717 = 2147497734
  • 37 + 2147497697 = 2147497734
  • 43 + 2147497691 = 2147497734
  • 71 + 2147497663 = 2147497734
  • 73 + 2147497661 = 2147497734
  • 163 + 2147497571 = 2147497734
  • 211 + 2147497523 = 2147497734
  • 227 + 2147497507 = 2147497734

Showing the first eight; more decompositions exist.
