Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621944, here are decompositions:

  • 43 + 33621901 = 33621944
  • 157 + 33621787 = 33621944
  • 163 + 33621781 = 33621944
  • 193 + 33621751 = 33621944
  • 271 + 33621673 = 33621944
  • 283 + 33621661 = 33621944
  • 547 + 33621397 = 33621944
  • 661 + 33621283 = 33621944

Showing the first eight; more decompositions exist.
