Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499920, here are decompositions:

  • 3 + 2147499917 = 2147499920
  • 37 + 2147499883 = 2147499920
  • 79 + 2147499841 = 2147499920
  • 193 + 2147499727 = 2147499920
  • 373 + 2147499547 = 2147499920
  • 409 + 2147499511 = 2147499920
  • 439 + 2147499481 = 2147499920
  • 463 + 2147499457 = 2147499920

Showing the first eight; more decompositions exist.
