Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489218, here are decompositions:

67 + 33489151 = 33489218
79 + 33489139 = 33489218
109 + 33489109 = 33489218
241 + 33488977 = 33489218
271 + 33488947 = 33489218
349 + 33488869 = 33489218
439 + 33488779 = 33489218
571 + 33488647 = 33489218

Showing the first eight; more decompositions exist.
