Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705072, here are decompositions:

  • 3 + 8705069 = 8705072
  • 31 + 8705041 = 8705072
  • 43 + 8705029 = 8705072
  • 151 + 8704921 = 8705072
  • 163 + 8704909 = 8705072
  • 349 + 8704723 = 8705072
  • 373 + 8704699 = 8705072
  • 421 + 8704651 = 8705072

Showing the first eight; more decompositions exist.
