Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551648, here are decompositions:

19 + 33551629 = 33551648
139 + 33551509 = 33551648
199 + 33551449 = 33551648
271 + 33551377 = 33551648
331 + 33551317 = 33551648
349 + 33551299 = 33551648
439 + 33551209 = 33551648
541 + 33551107 = 33551648

Showing the first eight; more decompositions exist.
