Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660842, here are decompositions:

  • 23 + 8660819 = 8660842
  • 89 + 8660753 = 8660842
  • 101 + 8660741 = 8660842
  • 149 + 8660693 = 8660842
  • 233 + 8660609 = 8660842
  • 263 + 8660579 = 8660842
  • 419 + 8660423 = 8660842
  • 461 + 8660381 = 8660842

Showing the first eight; more decompositions exist.
