Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650878, here are decompositions:

  • 29 + 8650849 = 8650878
  • 79 + 8650799 = 8650878
  • 101 + 8650777 = 8650878
  • 151 + 8650727 = 8650878
  • 157 + 8650721 = 8650878
  • 191 + 8650687 = 8650878
  • 211 + 8650667 = 8650878
  • 227 + 8650651 = 8650878

Showing the first eight; more decompositions exist.
