Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642912, here are decompositions:

  • 73 + 8642839 = 8642912
  • 139 + 8642773 = 8642912
  • 151 + 8642761 = 8642912
  • 331 + 8642581 = 8642912
  • 379 + 8642533 = 8642912
  • 463 + 8642449 = 8642912
  • 631 + 8642281 = 8642912
  • 739 + 8642173 = 8642912

Showing the first eight; more decompositions exist.
