Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669436, here are decompositions:

  • 19 + 8669417 = 8669436
  • 37 + 8669399 = 8669436
  • 43 + 8669393 = 8669436
  • 47 + 8669389 = 8669436
  • 103 + 8669333 = 8669436
  • 107 + 8669329 = 8669436
  • 157 + 8669279 = 8669436
  • 197 + 8669239 = 8669436

Showing the first eight; more decompositions exist.
