Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620970, here are decompositions:

  • 19 + 8620951 = 8620970
  • 73 + 8620897 = 8620970
  • 97 + 8620873 = 8620970
  • 109 + 8620861 = 8620970
  • 223 + 8620747 = 8620970
  • 283 + 8620687 = 8620970
  • 307 + 8620663 = 8620970
  • 331 + 8620639 = 8620970

Showing the first eight; more decompositions exist.
