Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680740, here are decompositions:

  • 7 + 8680733 = 8680740
  • 17 + 8680723 = 8680740
  • 23 + 8680717 = 8680740
  • 41 + 8680699 = 8680740
  • 43 + 8680697 = 8680740
  • 71 + 8680669 = 8680740
  • 109 + 8680631 = 8680740
  • 127 + 8680613 = 8680740

Showing the first eight; more decompositions exist.
