Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681550, here are decompositions:

  • 11 + 8681539 = 8681550
  • 37 + 8681513 = 8681550
  • 43 + 8681507 = 8681550
  • 47 + 8681503 = 8681550
  • 61 + 8681489 = 8681550
  • 67 + 8681483 = 8681550
  • 83 + 8681467 = 8681550
  • 103 + 8681447 = 8681550

Showing the first eight; more decompositions exist.
