Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485380, here are decompositions:

3 + 33485377 = 33485380
11 + 33485369 = 33485380
41 + 33485339 = 33485380
59 + 33485321 = 33485380
83 + 33485297 = 33485380
197 + 33485183 = 33485380
239 + 33485141 = 33485380
281 + 33485099 = 33485380

Showing the first eight; more decompositions exist.
