Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612834, here are decompositions:

  • 3 + 31612831 = 31612834
  • 101 + 31612733 = 31612834
  • 107 + 31612727 = 31612834
  • 167 + 31612667 = 31612834
  • 173 + 31612661 = 31612834
  • 251 + 31612583 = 31612834
  • 347 + 31612487 = 31612834
  • 353 + 31612481 = 31612834

Showing the first eight; more decompositions exist.
