Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33228, here are decompositions:

  • 5 + 33223 = 33228
  • 17 + 33211 = 33228
  • 29 + 33199 = 33228
  • 37 + 33191 = 33228
  • 47 + 33181 = 33228
  • 67 + 33161 = 33228
  • 79 + 33149 = 33228
  • 109 + 33119 = 33228

Showing the first eight; more decompositions exist.
