Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621802, here are decompositions:

  • 5 + 8621797 = 8621802
  • 23 + 8621779 = 8621802
  • 29 + 8621773 = 8621802
  • 53 + 8621749 = 8621802
  • 109 + 8621693 = 8621802
  • 149 + 8621653 = 8621802
  • 179 + 8621623 = 8621802
  • 193 + 8621609 = 8621802

Showing the first eight; more decompositions exist.
