Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681662, here are decompositions:

  • 23 + 8681639 = 8681662
  • 83 + 8681579 = 8681662
  • 113 + 8681549 = 8681662
  • 149 + 8681513 = 8681662
  • 173 + 8681489 = 8681662
  • 179 + 8681483 = 8681662
  • 233 + 8681429 = 8681662
  • 293 + 8681369 = 8681662

Showing the first eight; more decompositions exist.
