Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621722, here are decompositions:

  • 29 + 8621693 = 8621722
  • 41 + 8621681 = 8621722
  • 113 + 8621609 = 8621722
  • 269 + 8621453 = 8621722
  • 293 + 8621429 = 8621722
  • 311 + 8621411 = 8621722
  • 383 + 8621339 = 8621722
  • 479 + 8621243 = 8621722

Showing the first eight; more decompositions exist.
