Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553380, here are decompositions:

11 + 33553369 = 33553380
17 + 33553363 = 33553380
23 + 33553357 = 33553380
43 + 33553337 = 33553380
53 + 33553327 = 33553380
67 + 33553313 = 33553380
73 + 33553307 = 33553380
79 + 33553301 = 33553380

Showing the first eight; more decompositions exist.
