Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525680, here are decompositions:

37 + 33525643 = 33525680
61 + 33525619 = 33525680
73 + 33525607 = 33525680
109 + 33525571 = 33525680
127 + 33525553 = 33525680
151 + 33525529 = 33525680
163 + 33525517 = 33525680
193 + 33525487 = 33525680

Showing the first eight; more decompositions exist.
