Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533752, here are decompositions:

  • 31 + 31533721 = 31533752
  • 139 + 31533613 = 31533752
  • 181 + 31533571 = 31533752
  • 241 + 31533511 = 31533752
  • 373 + 31533379 = 31533752
  • 409 + 31533343 = 31533752
  • 619 + 31533133 = 31533752
  • 661 + 31533091 = 31533752

Showing the first eight; more decompositions exist.
