Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33536640, here are decompositions:

13 + 33536627 = 33536640
17 + 33536623 = 33536640
31 + 33536609 = 33536640
47 + 33536593 = 33536640
61 + 33536579 = 33536640
73 + 33536567 = 33536640
107 + 33536533 = 33536640
191 + 33536449 = 33536640

Showing the first eight; more decompositions exist.
