Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525980, here are decompositions:

31 + 33525949 = 33525980
79 + 33525901 = 33525980
97 + 33525883 = 33525980
109 + 33525871 = 33525980
223 + 33525757 = 33525980
337 + 33525643 = 33525980
373 + 33525607 = 33525980
409 + 33525571 = 33525980

Showing the first eight; more decompositions exist.
