Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537500, here are decompositions:

  • 67 + 33537433 = 33537500
  • 103 + 33537397 = 33537500
  • 313 + 33537187 = 33537500
  • 379 + 33537121 = 33537500
  • 397 + 33537103 = 33537500
  • 439 + 33537061 = 33537500
  • 613 + 33536887 = 33537500
  • 691 + 33536809 = 33537500

Showing the first eight; more decompositions exist.
