Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550820, here are decompositions:

97 + 33550723 = 33550820
157 + 33550663 = 33550820
229 + 33550591 = 33550820
307 + 33550513 = 33550820
379 + 33550441 = 33550820
439 + 33550381 = 33550820
607 + 33550213 = 33550820
619 + 33550201 = 33550820

Showing the first eight; more decompositions exist.
