Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551786, here are decompositions:

3 + 33551783 = 33551786
13 + 33551773 = 33551786
67 + 33551719 = 33551786
109 + 33551677 = 33551786
157 + 33551629 = 33551786
193 + 33551593 = 33551786
277 + 33551509 = 33551786
337 + 33551449 = 33551786

Showing the first eight; more decompositions exist.
