Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709980, here are decompositions:

  • 7 + 8709973 = 8709980
  • 61 + 8709919 = 8709980
  • 67 + 8709913 = 8709980
  • 109 + 8709871 = 8709980
  • 163 + 8709817 = 8709980
  • 199 + 8709781 = 8709980
  • 229 + 8709751 = 8709980
  • 283 + 8709697 = 8709980

Showing the first eight; more decompositions exist.
