Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497638, here are decompositions:

29 + 33497609 = 33497638
59 + 33497579 = 33497638
71 + 33497567 = 33497638
89 + 33497549 = 33497638
131 + 33497507 = 33497638
191 + 33497447 = 33497638
197 + 33497441 = 33497638
359 + 33497279 = 33497638

Showing the first eight; more decompositions exist.
