Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498660, here are decompositions:

  • 3 + 2147498657 = 2147498660
  • 7 + 2147498653 = 2147498660
  • 31 + 2147498629 = 2147498660
  • 67 + 2147498593 = 2147498660
  • 79 + 2147498581 = 2147498660
  • 211 + 2147498449 = 2147498660
  • 313 + 2147498347 = 2147498660
  • 739 + 2147497921 = 2147498660

Showing the first eight; more decompositions exist.
