Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498672, here are decompositions:

  • 13 + 2147498659 = 2147498672
  • 19 + 2147498653 = 2147498672
  • 43 + 2147498629 = 2147498672
  • 79 + 2147498593 = 2147498672
  • 223 + 2147498449 = 2147498672
  • 331 + 2147498341 = 2147498672
  • 463 + 2147498209 = 2147498672
  • 733 + 2147497939 = 2147498672

Showing the first eight; more decompositions exist.
