Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551438, here are decompositions:

61 + 33551377 = 33551438
139 + 33551299 = 33551438
181 + 33551257 = 33551438
229 + 33551209 = 33551438
331 + 33551107 = 33551438
397 + 33551041 = 33551438
457 + 33550981 = 33551438
499 + 33550939 = 33551438

Showing the first eight; more decompositions exist.
