Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668840, here are decompositions:

  • 3 + 8668837 = 8668840
  • 23 + 8668817 = 8668840
  • 41 + 8668799 = 8668840
  • 101 + 8668739 = 8668840
  • 197 + 8668643 = 8668840
  • 227 + 8668613 = 8668840
  • 263 + 8668577 = 8668840
  • 269 + 8668571 = 8668840

Showing the first eight; more decompositions exist.
