Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505580, here are decompositions:

7 + 33505573 = 33505580
13 + 33505567 = 33505580
37 + 33505543 = 33505580
61 + 33505519 = 33505580
139 + 33505441 = 33505580
271 + 33505309 = 33505580
457 + 33505123 = 33505580
463 + 33505117 = 33505580

Showing the first eight; more decompositions exist.
