Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557580, here are decompositions:

13 + 33557567 = 33557580
19 + 33557561 = 33557580
37 + 33557543 = 33557580
59 + 33557521 = 33557580
71 + 33557509 = 33557580
109 + 33557471 = 33557580
113 + 33557467 = 33557580
127 + 33557453 = 33557580

Showing the first eight; more decompositions exist.
