Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545438, here are decompositions:

37 + 33545401 = 33545438
61 + 33545377 = 33545438
67 + 33545371 = 33545438
109 + 33545329 = 33545438
127 + 33545311 = 33545438
211 + 33545227 = 33545438
271 + 33545167 = 33545438
337 + 33545101 = 33545438

Showing the first eight; more decompositions exist.
