Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553100, here are decompositions:

  • 43 + 33553057 = 33553100
  • 73 + 33553027 = 33553100
  • 151 + 33552949 = 33553100
  • 241 + 33552859 = 33553100
  • 271 + 33552829 = 33553100
  • 277 + 33552823 = 33553100
  • 313 + 33552787 = 33553100
  • 379 + 33552721 = 33553100

Showing the first eight; more decompositions exist.
