Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612106, here are decompositions:

  • 37 + 31612069 = 31612106
  • 109 + 31611997 = 31612106
  • 199 + 31611907 = 31612106
  • 223 + 31611883 = 31612106
  • 277 + 31611829 = 31612106
  • 349 + 31611757 = 31612106
  • 373 + 31611733 = 31612106
  • 397 + 31611709 = 31612106

Showing the first eight; more decompositions exist.
