Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681722, here are decompositions:

  • 29 + 8681693 = 8681722
  • 53 + 8681669 = 8681722
  • 59 + 8681663 = 8681722
  • 83 + 8681639 = 8681722
  • 173 + 8681549 = 8681722
  • 233 + 8681489 = 8681722
  • 239 + 8681483 = 8681722
  • 293 + 8681429 = 8681722

Showing the first eight; more decompositions exist.
