Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661682, here are decompositions:

  • 41 + 8661641 = 8661682
  • 53 + 8661629 = 8661682
  • 59 + 8661623 = 8661682
  • 101 + 8661581 = 8661682
  • 173 + 8661509 = 8661682
  • 191 + 8661491 = 8661682
  • 269 + 8661413 = 8661682
  • 401 + 8661281 = 8661682

Showing the first eight; more decompositions exist.
