Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497994, here are decompositions:

  • 73 + 2147497921 = 2147497994
  • 223 + 2147497771 = 2147497994
  • 277 + 2147497717 = 2147497994
  • 331 + 2147497663 = 2147497994
  • 487 + 2147497507 = 2147497994
  • 547 + 2147497447 = 2147497994
  • 601 + 2147497393 = 2147497994
  • 673 + 2147497321 = 2147497994

Showing the first eight; more decompositions exist.
