Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545372, here are decompositions:

43 + 33545329 = 33545372
61 + 33545311 = 33545372
181 + 33545191 = 33545372
199 + 33545173 = 33545372
271 + 33545101 = 33545372
373 + 33544999 = 33545372
379 + 33544993 = 33545372
433 + 33544939 = 33545372

Showing the first eight; more decompositions exist.
