Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545442, here are decompositions:

13 + 33545429 = 33545442
19 + 33545423 = 33545442
41 + 33545401 = 33545442
53 + 33545389 = 33545442
59 + 33545383 = 33545442
61 + 33545381 = 33545442
71 + 33545371 = 33545442
109 + 33545333 = 33545442

Showing the first eight; more decompositions exist.
