Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485680, here are decompositions:

17 + 33485663 = 33485680
113 + 33485567 = 33485680
167 + 33485513 = 33485680
197 + 33485483 = 33485680
281 + 33485399 = 33485680
311 + 33485369 = 33485680
359 + 33485321 = 33485680
383 + 33485297 = 33485680

Showing the first eight; more decompositions exist.
