Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551812, here are decompositions:

11 + 33551801 = 33551812
29 + 33551783 = 33551812
53 + 33551759 = 33551812
71 + 33551741 = 33551812
269 + 33551543 = 33551812
293 + 33551519 = 33551812
311 + 33551501 = 33551812
353 + 33551459 = 33551812

Showing the first eight; more decompositions exist.
