Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612672, here are decompositions:

  • 5 + 31612667 = 31612672
  • 11 + 31612661 = 31612672
  • 53 + 31612619 = 31612672
  • 83 + 31612589 = 31612672
  • 89 + 31612583 = 31612672
  • 191 + 31612481 = 31612672
  • 281 + 31612391 = 31612672
  • 359 + 31612313 = 31612672

Showing the first eight; more decompositions exist.
