Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33575640, here are decompositions:

13 + 33575627 = 33575640
17 + 33575623 = 33575640
19 + 33575621 = 33575640
61 + 33575579 = 33575640
83 + 33575557 = 33575640
89 + 33575551 = 33575640
103 + 33575537 = 33575640
127 + 33575513 = 33575640

Showing the first eight; more decompositions exist.
