Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485378, here are decompositions:

37 + 33485341 = 33485378
61 + 33485317 = 33485378
67 + 33485311 = 33485378
79 + 33485299 = 33485378
97 + 33485281 = 33485378
109 + 33485269 = 33485378
127 + 33485251 = 33485378
211 + 33485167 = 33485378

Showing the first eight; more decompositions exist.
