Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551390, here are decompositions:

13 + 33551377 = 33551390
73 + 33551317 = 33551390
181 + 33551209 = 33551390
211 + 33551179 = 33551390
277 + 33551113 = 33551390
283 + 33551107 = 33551390
337 + 33551053 = 33551390
349 + 33551041 = 33551390

Showing the first eight; more decompositions exist.
