Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503580, here are decompositions:

7 + 33503573 = 33503580
23 + 33503557 = 33503580
37 + 33503543 = 33503580
41 + 33503539 = 33503580
127 + 33503453 = 33503580
137 + 33503443 = 33503580
151 + 33503429 = 33503580
179 + 33503401 = 33503580

Showing the first eight; more decompositions exist.
