Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485490, here are decompositions:

7 + 33485483 = 33485490
13 + 33485477 = 33485490
47 + 33485443 = 33485490
107 + 33485383 = 33485490
109 + 33485381 = 33485490
113 + 33485377 = 33485490
149 + 33485341 = 33485490
151 + 33485339 = 33485490

Showing the first eight; more decompositions exist.
