Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511072, here are decompositions:

5 + 33511067 = 33511072
29 + 33511043 = 33511072
53 + 33511019 = 33511072
59 + 33511013 = 33511072
83 + 33510989 = 33511072
149 + 33510923 = 33511072
239 + 33510833 = 33511072
251 + 33510821 = 33511072

Showing the first eight; more decompositions exist.
