Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525666, here are decompositions:

19 + 33525647 = 33525666
23 + 33525643 = 33525666
47 + 33525619 = 33525666
59 + 33525607 = 33525666
73 + 33525593 = 33525666
113 + 33525553 = 33525666
137 + 33525529 = 33525666
149 + 33525517 = 33525666

Showing the first eight; more decompositions exist.
