Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524316, here are decompositions:

  • 23 + 31524293 = 31524316
  • 59 + 31524257 = 31524316
  • 149 + 31524167 = 31524316
  • 269 + 31524047 = 31524316
  • 293 + 31524023 = 31524316
  • 563 + 31523753 = 31524316
  • 647 + 31523669 = 31524316
  • 683 + 31523633 = 31524316

Showing the first eight; more decompositions exist.
