Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553170, here are decompositions:

  • 17 + 33553153 = 33553170
  • 19 + 33553151 = 33553170
  • 29 + 33553141 = 33553170
  • 67 + 33553103 = 33553170
  • 113 + 33553057 = 33553170
  • 223 + 33552947 = 33553170
  • 311 + 33552859 = 33553170
  • 317 + 33552853 = 33553170

Showing the first eight; more decompositions exist.
