Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621950, here are decompositions:

  • 3 + 8621947 = 8621950
  • 11 + 8621939 = 8621950
  • 17 + 8621933 = 8621950
  • 23 + 8621927 = 8621950
  • 53 + 8621897 = 8621950
  • 83 + 8621867 = 8621950
  • 89 + 8621861 = 8621950
  • 107 + 8621843 = 8621950

Showing the first eight; more decompositions exist.
