Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748920, here are decompositions:

  • 31 + 8748889 = 8748920
  • 43 + 8748877 = 8748920
  • 67 + 8748853 = 8748920
  • 73 + 8748847 = 8748920
  • 79 + 8748841 = 8748920
  • 109 + 8748811 = 8748920
  • 181 + 8748739 = 8748920
  • 211 + 8748709 = 8748920

Showing the first eight; more decompositions exist.
