Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666430, here are decompositions:

  • 11 + 8666419 = 8666430
  • 13 + 8666417 = 8666430
  • 37 + 8666393 = 8666430
  • 43 + 8666387 = 8666430
  • 61 + 8666369 = 8666430
  • 79 + 8666351 = 8666430
  • 83 + 8666347 = 8666430
  • 103 + 8666327 = 8666430

Showing the first eight; more decompositions exist.
