Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497782, here are decompositions:

  • 11 + 2147497771 = 2147497782
  • 13 + 2147497769 = 2147497782
  • 83 + 2147497699 = 2147497782
  • 211 + 2147497571 = 2147497782
  • 223 + 2147497559 = 2147497782
  • 293 + 2147497489 = 2147497782
  • 379 + 2147497403 = 2147497782
  • 389 + 2147497393 = 2147497782

Showing the first eight; more decompositions exist.
