Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498690, here are decompositions:

  • 13 + 2147498677 = 2147498690
  • 31 + 2147498659 = 2147498690
  • 37 + 2147498653 = 2147498690
  • 61 + 2147498629 = 2147498690
  • 97 + 2147498593 = 2147498690
  • 109 + 2147498581 = 2147498690
  • 241 + 2147498449 = 2147498690
  • 277 + 2147498413 = 2147498690

Showing the first eight; more decompositions exist.
