Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538372, here are decompositions:

5 + 33538367 = 33538372
29 + 33538343 = 33538372
59 + 33538313 = 33538372
113 + 33538259 = 33538372
149 + 33538223 = 33538372
239 + 33538133 = 33538372
269 + 33538103 = 33538372
281 + 33538091 = 33538372

Showing the first eight; more decompositions exist.
