Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642894, here are decompositions:

  • 31 + 8642863 = 8642894
  • 37 + 8642857 = 8642894
  • 313 + 8642581 = 8642894
  • 613 + 8642281 = 8642894
  • 787 + 8642107 = 8642894
  • 907 + 8641987 = 8642894
  • 937 + 8641957 = 8642894
  • 1021 + 8641873 = 8642894

Showing the first eight; more decompositions exist.
