Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668506, here are decompositions:

  • 5 + 8668501 = 8668506
  • 17 + 8668489 = 8668506
  • 23 + 8668483 = 8668506
  • 47 + 8668459 = 8668506
  • 83 + 8668423 = 8668506
  • 103 + 8668403 = 8668506
  • 127 + 8668379 = 8668506
  • 137 + 8668369 = 8668506

Showing the first eight; more decompositions exist.
