Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481760, here are decompositions:

  • 3 + 33481757 = 33481760
  • 7 + 33481753 = 33481760
  • 31 + 33481729 = 33481760
  • 163 + 33481597 = 33481760
  • 211 + 33481549 = 33481760
  • 331 + 33481429 = 33481760
  • 337 + 33481423 = 33481760
  • 409 + 33481351 = 33481760

Showing the first eight; more decompositions exist.
