Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485778, here are decompositions:

5 + 33485773 = 33485778
37 + 33485741 = 33485778
47 + 33485731 = 33485778
61 + 33485717 = 33485778
89 + 33485689 = 33485778
211 + 33485567 = 33485778
241 + 33485537 = 33485778
251 + 33485527 = 33485778

Showing the first eight; more decompositions exist.
