Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491866, here are decompositions:

17 + 33491849 = 33491866
29 + 33491837 = 33491866
137 + 33491729 = 33491866
173 + 33491693 = 33491866
227 + 33491639 = 33491866
263 + 33491603 = 33491866
449 + 33491417 = 33491866
479 + 33491387 = 33491866

Showing the first eight; more decompositions exist.
