Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619722, here are decompositions:

  • 3 + 8619719 = 8619722
  • 61 + 8619661 = 8619722
  • 73 + 8619649 = 8619722
  • 211 + 8619511 = 8619722
  • 283 + 8619439 = 8619722
  • 379 + 8619343 = 8619722
  • 499 + 8619223 = 8619722
  • 523 + 8619199 = 8619722

Showing the first eight; more decompositions exist.
