Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491988, here are decompositions:

7 + 33491981 = 33491988
11 + 33491977 = 33491988
29 + 33491959 = 33491988
59 + 33491929 = 33491988
71 + 33491917 = 33491988
139 + 33491849 = 33491988
151 + 33491837 = 33491988
157 + 33491831 = 33491988

Showing the first eight; more decompositions exist.
