Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545520, here are decompositions:

23 + 33545497 = 33545520
37 + 33545483 = 33545520
61 + 33545459 = 33545520
97 + 33545423 = 33545520
131 + 33545389 = 33545520
137 + 33545383 = 33545520
139 + 33545381 = 33545520
149 + 33545371 = 33545520

Showing the first eight; more decompositions exist.
