Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506580, here are decompositions:

7 + 33506573 = 33506580
11 + 33506569 = 33506580
17 + 33506563 = 33506580
31 + 33506549 = 33506580
59 + 33506521 = 33506580
71 + 33506509 = 33506580
101 + 33506479 = 33506580
103 + 33506477 = 33506580

Showing the first eight; more decompositions exist.
