Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533606, here are decompositions:

  • 7 + 31533599 = 31533606
  • 19 + 31533587 = 31533606
  • 43 + 31533563 = 31533606
  • 59 + 31533547 = 31533606
  • 73 + 31533533 = 31533606
  • 89 + 31533517 = 31533606
  • 107 + 31533499 = 31533606
  • 109 + 31533497 = 31533606

Showing the first eight; more decompositions exist.
