Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623894, here are decompositions:

  • 37 + 33623857 = 33623894
  • 43 + 33623851 = 33623894
  • 61 + 33623833 = 33623894
  • 97 + 33623797 = 33623894
  • 103 + 33623791 = 33623894
  • 193 + 33623701 = 33623894
  • 307 + 33623587 = 33623894
  • 331 + 33623563 = 33623894

Showing the first eight; more decompositions exist.
