Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498876, here are decompositions:

  • 79 + 2147498797 = 2147498876
  • 109 + 2147498767 = 2147498876
  • 139 + 2147498737 = 2147498876
  • 199 + 2147498677 = 2147498876
  • 223 + 2147498653 = 2147498876
  • 283 + 2147498593 = 2147498876
  • 463 + 2147498413 = 2147498876
  • 937 + 2147497939 = 2147498876

Showing the first eight; more decompositions exist.
