Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621498, here are decompositions:

  • 7 + 8621491 = 8621498
  • 19 + 8621479 = 8621498
  • 31 + 8621467 = 8621498
  • 199 + 8621299 = 8621498
  • 397 + 8621101 = 8621498
  • 409 + 8621089 = 8621498
  • 421 + 8621077 = 8621498
  • 547 + 8620951 = 8621498

Showing the first eight; more decompositions exist.
