Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566680, here are decompositions:

3 + 33566677 = 33566680
11 + 33566669 = 33566680
23 + 33566657 = 33566680
71 + 33566609 = 33566680
101 + 33566579 = 33566680
131 + 33566549 = 33566680
233 + 33566447 = 33566680
281 + 33566399 = 33566680

Showing the first eight; more decompositions exist.
