Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621400, here are decompositions:

  • 3 + 33621397 = 33621400
  • 11 + 33621389 = 33621400
  • 17 + 33621383 = 33621400
  • 89 + 33621311 = 33621400
  • 101 + 33621299 = 33621400
  • 149 + 33621251 = 33621400
  • 167 + 33621233 = 33621400
  • 227 + 33621173 = 33621400

Showing the first eight; more decompositions exist.
