Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147591626, here are decompositions:

  • 107 + 2147591519 = 2147591626
  • 149 + 2147591477 = 2147591626
  • 239 + 2147591387 = 2147591626
  • 347 + 2147591279 = 2147591626
  • 353 + 2147591273 = 2147591626
  • 617 + 2147591009 = 2147591626
  • 647 + 2147590979 = 2147591626
  • 659 + 2147590967 = 2147591626

Showing the first eight; more decompositions exist.
