Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658628, here are decompositions:

  • 47 + 8658581 = 8658628
  • 59 + 8658569 = 8658628
  • 101 + 8658527 = 8658628
  • 197 + 8658431 = 8658628
  • 257 + 8658371 = 8658628
  • 467 + 8658161 = 8658628
  • 491 + 8658137 = 8658628
  • 521 + 8658107 = 8658628

Showing the first eight; more decompositions exist.
