Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467738, here are decompositions:

  • 5 + 2147467733 = 2147467738
  • 41 + 2147467697 = 2147467738
  • 71 + 2147467667 = 2147467738
  • 107 + 2147467631 = 2147467738
  • 179 + 2147467559 = 2147467738
  • 359 + 2147467379 = 2147467738
  • 569 + 2147467169 = 2147467738
  • 617 + 2147467121 = 2147467738

Showing the first eight; more decompositions exist.
