Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680940, here are decompositions:

  • 19 + 8680921 = 8680940
  • 31 + 8680909 = 8680940
  • 127 + 8680813 = 8680940
  • 139 + 8680801 = 8680940
  • 199 + 8680741 = 8680940
  • 223 + 8680717 = 8680940
  • 241 + 8680699 = 8680940
  • 271 + 8680669 = 8680940

Showing the first eight; more decompositions exist.
