Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566490, here are decompositions:

17 + 33566473 = 33566490
29 + 33566461 = 33566490
43 + 33566447 = 33566490
59 + 33566431 = 33566490
71 + 33566419 = 33566490
103 + 33566387 = 33566490
107 + 33566383 = 33566490
137 + 33566353 = 33566490

Showing the first eight; more decompositions exist.
