Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680680, here are decompositions:

  • 11 + 8680669 = 8680680
  • 61 + 8680619 = 8680680
  • 67 + 8680613 = 8680680
  • 79 + 8680601 = 8680680
  • 97 + 8680583 = 8680680
  • 137 + 8680543 = 8680680
  • 167 + 8680513 = 8680680
  • 179 + 8680501 = 8680680

Showing the first eight; more decompositions exist.
