Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538512, here are decompositions:

5 + 33538507 = 33538512
13 + 33538499 = 33538512
31 + 33538481 = 33538512
43 + 33538469 = 33538512
71 + 33538441 = 33538512
109 + 33538403 = 33538512
173 + 33538339 = 33538512
191 + 33538321 = 33538512

Showing the first eight; more decompositions exist.
