Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33280, here are decompositions:

  • 89 + 33191 = 33280
  • 101 + 33179 = 33280
  • 131 + 33149 = 33280
  • 167 + 33113 = 33280
  • 173 + 33107 = 33280
  • 197 + 33083 = 33280
  • 227 + 33053 = 33280
  • 251 + 33029 = 33280

Showing the first eight; more decompositions exist.
