Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525580, here are decompositions:

29 + 33525551 = 33525580
47 + 33525533 = 33525580
89 + 33525491 = 33525580
131 + 33525449 = 33525580
239 + 33525341 = 33525580
269 + 33525311 = 33525580
281 + 33525299 = 33525580
293 + 33525287 = 33525580

Showing the first eight; more decompositions exist.
