Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623388, here are decompositions:

17 + 33623371 = 33623388
31 + 33623357 = 33623388
37 + 33623351 = 33623388
47 + 33623341 = 33623388
59 + 33623329 = 33623388
61 + 33623327 = 33623388
89 + 33623299 = 33623388
101 + 33623287 = 33623388

Showing the first eight; more decompositions exist.
