Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485420, here are decompositions:

37 + 33485383 = 33485420
43 + 33485377 = 33485420
79 + 33485341 = 33485420
97 + 33485323 = 33485420
103 + 33485317 = 33485420
109 + 33485311 = 33485420
139 + 33485281 = 33485420
151 + 33485269 = 33485420

Showing the first eight; more decompositions exist.
