Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497868, here are decompositions:

  • 97 + 2147497771 = 2147497868
  • 151 + 2147497717 = 2147497868
  • 379 + 2147497489 = 2147497868
  • 409 + 2147497459 = 2147497868
  • 421 + 2147497447 = 2147497868
  • 457 + 2147497411 = 2147497868
  • 547 + 2147497321 = 2147497868
  • 631 + 2147497237 = 2147497868

Showing the first eight; more decompositions exist.
