Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33603840, here are decompositions:

  • 7 + 33603833 = 33603840
  • 43 + 33603797 = 33603840
  • 73 + 33603767 = 33603840
  • 89 + 33603751 = 33603840
  • 97 + 33603743 = 33603840
  • 223 + 33603617 = 33603840
  • 241 + 33603599 = 33603840
  • 251 + 33603589 = 33603840

Showing the first eight; more decompositions exist.
