Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33565580, here are decompositions:

3 + 33565577 = 33565580
73 + 33565507 = 33565580
211 + 33565369 = 33565580
241 + 33565339 = 33565580
409 + 33565171 = 33565580
439 + 33565141 = 33565580
571 + 33565009 = 33565580
823 + 33564757 = 33565580

Showing the first eight; more decompositions exist.
