Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621512, here are decompositions:

  • 103 + 33621409 = 33621512
  • 151 + 33621361 = 33621512
  • 229 + 33621283 = 33621512
  • 349 + 33621163 = 33621512
  • 601 + 33620911 = 33621512
  • 709 + 33620803 = 33621512
  • 751 + 33620761 = 33621512
  • 823 + 33620689 = 33621512

Showing the first eight; more decompositions exist.
