Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709420, here are decompositions:

  • 37 + 8709383 = 8709420
  • 43 + 8709377 = 8709420
  • 47 + 8709373 = 8709420
  • 59 + 8709361 = 8709420
  • 103 + 8709317 = 8709420
  • 107 + 8709313 = 8709420
  • 131 + 8709289 = 8709420
  • 149 + 8709271 = 8709420

Showing the first eight; more decompositions exist.
