Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497892, here are decompositions:

  • 3 + 2147497889 = 2147497892
  • 193 + 2147497699 = 2147497892
  • 229 + 2147497663 = 2147497892
  • 433 + 2147497459 = 2147497892
  • 499 + 2147497393 = 2147497892
  • 571 + 2147497321 = 2147497892
  • 691 + 2147497201 = 2147497892
  • 751 + 2147497141 = 2147497892

Showing the first eight; more decompositions exist.
