Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147542318, here are decompositions:

  • 17 + 2147542301 = 2147542318
  • 41 + 2147542277 = 2147542318
  • 107 + 2147542211 = 2147542318
  • 281 + 2147542037 = 2147542318
  • 479 + 2147541839 = 2147542318
  • 557 + 2147541761 = 2147542318
  • 569 + 2147541749 = 2147542318
  • 617 + 2147541701 = 2147542318

Showing the first eight; more decompositions exist.
