Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681694, here are decompositions:

  • 31 + 8681663 = 8681694
  • 71 + 8681623 = 8681694
  • 107 + 8681587 = 8681694
  • 127 + 8681567 = 8681694
  • 181 + 8681513 = 8681694
  • 191 + 8681503 = 8681694
  • 211 + 8681483 = 8681694
  • 227 + 8681467 = 8681694

Showing the first eight; more decompositions exist.
