Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147465378, here are decompositions:

  • 139 + 2147465239 = 2147465378
  • 151 + 2147465227 = 2147465378
  • 181 + 2147465197 = 2147465378
  • 571 + 2147464807 = 2147465378
  • 601 + 2147464777 = 2147465378
  • 631 + 2147464747 = 2147465378
  • 691 + 2147464687 = 2147465378
  • 769 + 2147464609 = 2147465378

Showing the first eight; more decompositions exist.
