Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621510, here are decompositions:

  • 19 + 8621491 = 8621510
  • 31 + 8621479 = 8621510
  • 43 + 8621467 = 8621510
  • 67 + 8621443 = 8621510
  • 97 + 8621413 = 8621510
  • 211 + 8621299 = 8621510
  • 229 + 8621281 = 8621510
  • 367 + 8621143 = 8621510

Showing the first eight; more decompositions exist.
