Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566520, here are decompositions:

23 + 33566497 = 33566520
47 + 33566473 = 33566520
59 + 33566461 = 33566520
73 + 33566447 = 33566520
89 + 33566431 = 33566520
101 + 33566419 = 33566520
137 + 33566383 = 33566520
149 + 33566371 = 33566520

Showing the first eight; more decompositions exist.
