Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493638, here are decompositions:

11 + 33493627 = 33493638
19 + 33493619 = 33493638
37 + 33493601 = 33493638
47 + 33493591 = 33493638
71 + 33493567 = 33493638
89 + 33493549 = 33493638
97 + 33493541 = 33493638
109 + 33493529 = 33493638

Showing the first eight; more decompositions exist.
