Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661480, here are decompositions:

  • 11 + 8661469 = 8661480
  • 19 + 8661461 = 8661480
  • 41 + 8661439 = 8661480
  • 43 + 8661437 = 8661480
  • 53 + 8661427 = 8661480
  • 67 + 8661413 = 8661480
  • 73 + 8661407 = 8661480
  • 97 + 8661383 = 8661480

Showing the first eight; more decompositions exist.
