Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612500, here are decompositions:

  • 13 + 33612487 = 33612500
  • 43 + 33612457 = 33612500
  • 67 + 33612433 = 33612500
  • 211 + 33612289 = 33612500
  • 283 + 33612217 = 33612500
  • 349 + 33612151 = 33612500
  • 421 + 33612079 = 33612500
  • 541 + 33611959 = 33612500

Showing the first eight; more decompositions exist.
