Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479200, here are decompositions:

  • 59 + 33479141 = 33479200
  • 137 + 33479063 = 33479200
  • 197 + 33479003 = 33479200
  • 257 + 33478943 = 33479200
  • 311 + 33478889 = 33479200
  • 449 + 33478751 = 33479200
  • 479 + 33478721 = 33479200
  • 593 + 33478607 = 33479200

Showing the first eight; more decompositions exist.
