Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497850, here are decompositions:

  • 79 + 2147497771 = 2147497850
  • 151 + 2147497699 = 2147497850
  • 439 + 2147497411 = 2147497850
  • 457 + 2147497393 = 2147497850
  • 607 + 2147497243 = 2147497850
  • 613 + 2147497237 = 2147497850
  • 709 + 2147497141 = 2147497850
  • 769 + 2147497081 = 2147497850

Showing the first eight; more decompositions exist.
