Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481720, here are decompositions:

  • 149 + 33481571 = 33481720
  • 353 + 33481367 = 33481720
  • 359 + 33481361 = 33481720
  • 431 + 33481289 = 33481720
  • 557 + 33481163 = 33481720
  • 647 + 33481073 = 33481720
  • 653 + 33481067 = 33481720
  • 683 + 33481037 = 33481720

Showing the first eight; more decompositions exist.
