Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649800, here are decompositions:

  • 7 + 8649793 = 8649800
  • 37 + 8649763 = 8649800
  • 43 + 8649757 = 8649800
  • 79 + 8649721 = 8649800
  • 97 + 8649703 = 8649800
  • 109 + 8649691 = 8649800
  • 139 + 8649661 = 8649800
  • 163 + 8649637 = 8649800

Showing the first eight; more decompositions exist.
