Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612124, here are decompositions:

  • 3 + 31612121 = 31612124
  • 43 + 31612081 = 31612124
  • 127 + 31611997 = 31612124
  • 241 + 31611883 = 31612124
  • 283 + 31611841 = 31612124
  • 307 + 31611817 = 31612124
  • 367 + 31611757 = 31612124
  • 421 + 31611703 = 31612124

Showing the first eight; more decompositions exist.
