Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621010, here are decompositions:

  • 17 + 8620993 = 8621010
  • 37 + 8620973 = 8621010
  • 59 + 8620951 = 8621010
  • 61 + 8620949 = 8621010
  • 67 + 8620943 = 8621010
  • 113 + 8620897 = 8621010
  • 137 + 8620873 = 8621010
  • 149 + 8620861 = 8621010

Showing the first eight; more decompositions exist.
