Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485740, here are decompositions:

23 + 33485717 = 33485740
53 + 33485687 = 33485740
173 + 33485567 = 33485740
227 + 33485513 = 33485740
257 + 33485483 = 33485740
263 + 33485477 = 33485740
359 + 33485381 = 33485740
401 + 33485339 = 33485740

Showing the first eight; more decompositions exist.
