Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666538, here are decompositions:

  • 5 + 8666533 = 8666538
  • 19 + 8666519 = 8666538
  • 37 + 8666501 = 8666538
  • 47 + 8666491 = 8666538
  • 59 + 8666479 = 8666538
  • 61 + 8666477 = 8666538
  • 79 + 8666459 = 8666538
  • 107 + 8666431 = 8666538

Showing the first eight; more decompositions exist.
