Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551818, here are decompositions:

17 + 33551801 = 33551818
59 + 33551759 = 33551818
101 + 33551717 = 33551818
191 + 33551627 = 33551818
317 + 33551501 = 33551818
359 + 33551459 = 33551818
401 + 33551417 = 33551818
449 + 33551369 = 33551818

Showing the first eight; more decompositions exist.
