Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523688, here are decompositions:

  • 19 + 33523669 = 33523688
  • 109 + 33523579 = 33523688
  • 241 + 33523447 = 33523688
  • 277 + 33523411 = 33523688
  • 307 + 33523381 = 33523688
  • 397 + 33523291 = 33523688
  • 547 + 33523141 = 33523688
  • 661 + 33523027 = 33523688

Showing the first eight; more decompositions exist.
