Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524524, here are decompositions:

  • 7 + 31524517 = 31524524
  • 181 + 31524343 = 31524524
  • 193 + 31524331 = 31524524
  • 223 + 31524301 = 31524524
  • 331 + 31524193 = 31524524
  • 433 + 31524091 = 31524524
  • 571 + 31523953 = 31524524
  • 607 + 31523917 = 31524524

Showing the first eight; more decompositions exist.
