Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33495720, here are decompositions:

19 + 33495701 = 33495720
23 + 33495697 = 33495720
43 + 33495677 = 33495720
67 + 33495653 = 33495720
113 + 33495607 = 33495720
151 + 33495569 = 33495720
173 + 33495547 = 33495720
211 + 33495509 = 33495720

Showing the first eight; more decompositions exist.
