Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566642, here are decompositions:

61 + 33566581 = 33566642
73 + 33566569 = 33566642
79 + 33566563 = 33566642
103 + 33566539 = 33566642
181 + 33566461 = 33566642
211 + 33566431 = 33566642
223 + 33566419 = 33566642
271 + 33566371 = 33566642

Showing the first eight; more decompositions exist.
