Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708220, here are decompositions:

  • 19 + 8708201 = 8708220
  • 23 + 8708197 = 8708220
  • 47 + 8708173 = 8708220
  • 61 + 8708159 = 8708220
  • 67 + 8708153 = 8708220
  • 127 + 8708093 = 8708220
  • 139 + 8708081 = 8708220
  • 149 + 8708071 = 8708220

Showing the first eight; more decompositions exist.
