Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670886, here are decompositions:

  • 17 + 8670869 = 8670886
  • 23 + 8670863 = 8670886
  • 113 + 8670773 = 8670886
  • 173 + 8670713 = 8670886
  • 233 + 8670653 = 8670886
  • 353 + 8670533 = 8670886
  • 383 + 8670503 = 8670886
  • 479 + 8670407 = 8670886

Showing the first eight; more decompositions exist.
