Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735220, here are decompositions:

  • 23 + 8735197 = 8735220
  • 37 + 8735183 = 8735220
  • 41 + 8735179 = 8735220
  • 83 + 8735137 = 8735220
  • 107 + 8735113 = 8735220
  • 173 + 8735047 = 8735220
  • 181 + 8735039 = 8735220
  • 191 + 8735029 = 8735220

Showing the first eight; more decompositions exist.
