Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497454, here are decompositions:

  • 7 + 2147497447 = 2147497454
  • 43 + 2147497411 = 2147497454
  • 61 + 2147497393 = 2147497454
  • 211 + 2147497243 = 2147497454
  • 313 + 2147497141 = 2147497454
  • 373 + 2147497081 = 2147497454
  • 457 + 2147496997 = 2147497454
  • 601 + 2147496853 = 2147497454

Showing the first eight; more decompositions exist.
