Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20550, here are decompositions:

  • 7 + 20543 = 20550
  • 17 + 20533 = 20550
  • 29 + 20521 = 20550
  • 41 + 20509 = 20550
  • 43 + 20507 = 20550
  • 67 + 20483 = 20550
  • 71 + 20479 = 20550
  • 73 + 20477 = 20550

Showing the first eight; more decompositions exist.
