Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478428, here are decompositions:

  • 7 + 33478421 = 33478428
  • 17 + 33478411 = 33478428
  • 37 + 33478391 = 33478428
  • 41 + 33478387 = 33478428
  • 97 + 33478331 = 33478428
  • 197 + 33478231 = 33478428
  • 227 + 33478201 = 33478428
  • 229 + 33478199 = 33478428

Showing the first eight; more decompositions exist.
