Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621016, here are decompositions:

  • 7 + 8621009 = 8621016
  • 23 + 8620993 = 8621016
  • 43 + 8620973 = 8621016
  • 67 + 8620949 = 8621016
  • 73 + 8620943 = 8621016
  • 269 + 8620747 = 8621016
  • 277 + 8620739 = 8621016
  • 293 + 8620723 = 8621016

Showing the first eight; more decompositions exist.
