Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605140, here are decompositions:

  • 79 + 8605061 = 8605140
  • 83 + 8605057 = 8605140
  • 139 + 8605001 = 8605140
  • 149 + 8604991 = 8605140
  • 157 + 8604983 = 8605140
  • 163 + 8604977 = 8605140
  • 179 + 8604961 = 8605140
  • 197 + 8604943 = 8605140

Showing the first eight; more decompositions exist.
