Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545538, here are decompositions:

11 + 33545527 = 33545538
41 + 33545497 = 33545538
79 + 33545459 = 33545538
109 + 33545429 = 33545538
137 + 33545401 = 33545538
149 + 33545389 = 33545538
157 + 33545381 = 33545538
167 + 33545371 = 33545538

Showing the first eight; more decompositions exist.
