Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20524, here are decompositions:

  • 3 + 20521 = 20524
  • 17 + 20507 = 20524
  • 41 + 20483 = 20524
  • 47 + 20477 = 20524
  • 83 + 20441 = 20524
  • 113 + 20411 = 20524
  • 131 + 20393 = 20524
  • 167 + 20357 = 20524

Showing the first eight; more decompositions exist.
