Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551990, here are decompositions:

7 + 33551983 = 33551990
13 + 33551977 = 33551990
19 + 33551971 = 33551990
37 + 33551953 = 33551990
97 + 33551893 = 33551990
151 + 33551839 = 33551990
193 + 33551797 = 33551990
271 + 33551719 = 33551990

Showing the first eight; more decompositions exist.
