Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620938, here are decompositions:

  • 41 + 8620897 = 8620938
  • 97 + 8620841 = 8620938
  • 181 + 8620757 = 8620938
  • 191 + 8620747 = 8620938
  • 199 + 8620739 = 8620938
  • 211 + 8620727 = 8620938
  • 251 + 8620687 = 8620938
  • 307 + 8620631 = 8620938

Showing the first eight; more decompositions exist.
