Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524136, here are decompositions:

  • 3 + 31524133 = 31524136
  • 29 + 31524107 = 31524136
  • 89 + 31524047 = 31524136
  • 113 + 31524023 = 31524136
  • 197 + 31523939 = 31524136
  • 383 + 31523753 = 31524136
  • 467 + 31523669 = 31524136
  • 503 + 31523633 = 31524136

Showing the first eight; more decompositions exist.
