Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621890, here are decompositions:

  • 31 + 33621859 = 33621890
  • 67 + 33621823 = 33621890
  • 103 + 33621787 = 33621890
  • 109 + 33621781 = 33621890
  • 139 + 33621751 = 33621890
  • 163 + 33621727 = 33621890
  • 199 + 33621691 = 33621890
  • 229 + 33621661 = 33621890

Showing the first eight; more decompositions exist.
