Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566640, here are decompositions:

31 + 33566609 = 33566640
53 + 33566587 = 33566640
59 + 33566581 = 33566640
61 + 33566579 = 33566640
71 + 33566569 = 33566640
83 + 33566557 = 33566640
101 + 33566539 = 33566640
167 + 33566473 = 33566640

Showing the first eight; more decompositions exist.
