Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33607220, here are decompositions:

  • 7 + 33607213 = 33607220
  • 139 + 33607081 = 33607220
  • 211 + 33607009 = 33607220
  • 223 + 33606997 = 33607220
  • 313 + 33606907 = 33607220
  • 331 + 33606889 = 33607220
  • 433 + 33606787 = 33607220
  • 547 + 33606673 = 33607220

Showing the first eight; more decompositions exist.
