Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537752, here are decompositions:

  • 5 + 31537747 = 31537752
  • 11 + 31537741 = 31537752
  • 31 + 31537721 = 31537752
  • 61 + 31537691 = 31537752
  • 149 + 31537603 = 31537752
  • 179 + 31537573 = 31537752
  • 193 + 31537559 = 31537752
  • 271 + 31537481 = 31537752

Showing the first eight; more decompositions exist.
