Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523780, here are decompositions:

11 + 33523769 = 33523780
23 + 33523757 = 33523780
29 + 33523751 = 33523780
53 + 33523727 = 33523780
83 + 33523697 = 33523780
179 + 33523601 = 33523780
197 + 33523583 = 33523780
281 + 33523499 = 33523780

Showing the first eight; more decompositions exist.
