Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669238, here are decompositions:

  • 5 + 8669233 = 8669238
  • 31 + 8669207 = 8669238
  • 59 + 8669179 = 8669238
  • 79 + 8669159 = 8669238
  • 131 + 8669107 = 8669238
  • 167 + 8669071 = 8669238
  • 197 + 8669041 = 8669238
  • 211 + 8669027 = 8669238

Showing the first eight; more decompositions exist.
