Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566580, here are decompositions:

11 + 33566569 = 33566580
17 + 33566563 = 33566580
23 + 33566557 = 33566580
31 + 33566549 = 33566580
41 + 33566539 = 33566580
83 + 33566497 = 33566580
107 + 33566473 = 33566580
149 + 33566431 = 33566580

Showing the first eight; more decompositions exist.
