Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524028, here are decompositions:

  • 5 + 31524023 = 31524028
  • 17 + 31524011 = 31524028
  • 89 + 31523939 = 31524028
  • 227 + 31523801 = 31524028
  • 359 + 31523669 = 31524028
  • 449 + 31523579 = 31524028
  • 491 + 31523537 = 31524028
  • 587 + 31523441 = 31524028

Showing the first eight; more decompositions exist.
