Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525144, here are decompositions:

7 + 33525137 = 33525144
53 + 33525091 = 33525144
67 + 33525077 = 33525144
83 + 33525061 = 33525144
127 + 33525017 = 33525144
131 + 33525013 = 33525144
167 + 33524977 = 33525144
173 + 33524971 = 33525144

Showing the first eight; more decompositions exist.
