Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33616388, here are decompositions:

7 + 33616381 = 33616388
31 + 33616357 = 33616388
151 + 33616237 = 33616388
181 + 33616207 = 33616388
199 + 33616189 = 33616388
241 + 33616147 = 33616388
331 + 33616057 = 33616388
397 + 33615991 = 33616388

Showing the first eight; more decompositions exist.
