Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545490, here are decompositions:

7 + 33545483 = 33545490
31 + 33545459 = 33545490
47 + 33545443 = 33545490
61 + 33545429 = 33545490
67 + 33545423 = 33545490
89 + 33545401 = 33545490
101 + 33545389 = 33545490
107 + 33545383 = 33545490

Showing the first eight; more decompositions exist.
