Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009806, here are decompositions:

  • 19 + 1009787 = 1009806
  • 59 + 1009747 = 1009806
  • 79 + 1009727 = 1009806
  • 137 + 1009669 = 1009806
  • 157 + 1009649 = 1009806
  • 163 + 1009643 = 1009806
  • 179 + 1009627 = 1009806
  • 197 + 1009609 = 1009806

Showing the first eight; more decompositions exist.
