Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669850, here are decompositions:

  • 19 + 8669831 = 8669850
  • 29 + 8669821 = 8669850
  • 73 + 8669777 = 8669850
  • 83 + 8669767 = 8669850
  • 149 + 8669701 = 8669850
  • 179 + 8669671 = 8669850
  • 181 + 8669669 = 8669850
  • 193 + 8669657 = 8669850

Showing the first eight; more decompositions exist.
