Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660386, here are decompositions:

  • 3 + 8660383 = 8660386
  • 5 + 8660381 = 8660386
  • 17 + 8660369 = 8660386
  • 47 + 8660339 = 8660386
  • 89 + 8660297 = 8660386
  • 197 + 8660189 = 8660386
  • 347 + 8660039 = 8660386
  • 353 + 8660033 = 8660386

Showing the first eight; more decompositions exist.
