Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619538, here are decompositions:

  • 29 + 8619509 = 8619538
  • 47 + 8619491 = 8619538
  • 101 + 8619437 = 8619538
  • 107 + 8619431 = 8619538
  • 269 + 8619269 = 8619538
  • 461 + 8619077 = 8619538
  • 467 + 8619071 = 8619538
  • 479 + 8619059 = 8619538

Showing the first eight; more decompositions exist.
