Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551620, here are decompositions:

101 + 33551519 = 33551620
107 + 33551513 = 33551620
251 + 33551369 = 33551620
257 + 33551363 = 33551620
317 + 33551303 = 33551620
359 + 33551261 = 33551620
383 + 33551237 = 33551620
449 + 33551171 = 33551620

Showing the first eight; more decompositions exist.
