Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542120, here are decompositions:

  • 19 + 33542101 = 33542120
  • 43 + 33542077 = 33542120
  • 97 + 33542023 = 33542120
  • 163 + 33541957 = 33542120
  • 181 + 33541939 = 33542120
  • 211 + 33541909 = 33542120
  • 349 + 33541771 = 33542120
  • 397 + 33541723 = 33542120

Showing the first eight; more decompositions exist.
